denveratsun Posted September 24, 2009 Report Share Posted September 24, 2009 P.S.--I have a set of these in stock right now due to a member ordering but not paying.:( :mad:That sucks man! Really nice work too...that really blows that they are not paying you. Keep up the nice work... I have just one quick question though (possible repeat...looked but didn't see it addressed:) Can I still run stock 521 14's with these arms and the attached HB/720 parts? Quote Link to comment
BEEBANI Posted September 24, 2009 Author Report Share Posted September 24, 2009 I think so, 720's came with 14's didn't they? Quote Link to comment

lowdatsun620 Posted October 26, 2009 Report Share Posted October 26, 2009 They use the 720/hardbody cross rod with bushings. Ok, before anybody starts hating, I've just used the search, and read all the main threads that discuss this swap, just to see if I missed the info the dozen times ive read them before and can't find anything specifically regarding this problem... if it's been answered, simply point me to the correct thread and I'll read it myself... ok? Thanks As mentioned in all other threads, as well as specifically instructed by Beebani when ordering, I am trying to use the Hardbody crossrods with his uppers, but I can't see how they are supposed to work for a couple reasons and am seriously wondering if I'm just a little slow since no one else seems to have had this problem... I'll start with what parts I picked up. I have everything from the upper cross rods to the complete spindle assembly off a V6 hardbody, not sure what year but it shouldnt matter from what I've found in posts, and am using a dropped hardbody LCA since my fabricator had a pair laying around and gave them to me for free. So here's the issue, the mounting bolts are WAY too wide. This pic was taken on the drivers side, and the rear mounting holes are aligned fore/aft and look how far forward the front hole is. So I thought maybe the V6 model was different so I checked against a HB that is at the fabricators and found it to be the same spacing. These pics are measuring hole centre to centre Mine (4 3/8"): Hardbody (4 3/8"): 620 (3 1/8"): Second issue, the HB crossrods and arms are wider at the bushings than the 620, but Beebanis arms are the same as a 620 and he told me himself to use 720/hb crossrods, as well as in this thread. Arm comparison: Thought maybe I was totally misunderstanding and supposed to use the 620 crossrod but the bushings on the 620 arm are definitely not the ones to use, no pic of them but you guys would know so anyway. The only thing I could think of was to disassemble my 620 crossrods from the arms and see if I could get the HB bushings onto the 620 crossrods and see how that works out, but I ran out of time and had to leave... Help! What am I doing wrong?:confused: Quote Link to comment
yello620 Posted October 26, 2009 Report Share Posted October 26, 2009 I haven't seen the instructions from Beebani, but the Hardbody shafts will not work. You need shafts from a 78/79 620(disc brakes trucks), or from a 80-85 720 truck. The upper control arm bushings are the same from 78-97, but the arms and shafts changed. Quote Link to comment
lowdatsun620 Posted October 26, 2009 Report Share Posted October 26, 2009 (edited) ok thanks, i had read 720 in Glengemans post, but Beebani told me HB and 720 were the same critical dimensions and had stated the same in posts. Anybody have a set of 720 crossrods available? Anybody making a trip to the junkyard soon? Pull me a set, I'll pay you back for them, pay for shipping and compensate you for your effort. ($ or have lots of 620 parts wont be needing now, except bodywork, just ask) Datsuns aren't nearly as easy to find here in Canada as for you guys in WA/OR and since I'm currently without a license, prowling the local yards isn't all that easy. Would be much appreciated. Will post in classifieds too. Thanks again Yello Edited October 26, 2009 by lowdatsun620 added request Quote Link to comment
BEEBANI Posted October 26, 2009 Author Report Share Posted October 26, 2009 Well, apparantley I got some bad info also. The ones I modeled these after, which are also on my old 620 were from a '85 that Glen had given me, and I was told that the hb's were the same. Sorry about the confusion man. Quote Link to comment

datsun4dsc Posted October 28, 2009 Report Share Posted October 28, 2009 Beebani Can we get a well documented procedure and parts needed to install this on a 521? Most of the write up is done on a 620 and very little info on 521 installation. Pictures would help also thanks Quote Link to comment
slodat Posted October 28, 2009 Report Share Posted October 28, 2009 The 521 should be the same as the 620. Quote Link to comment
521newbie Posted October 28, 2009 Report Share Posted October 28, 2009 I'm getting the last of the parts together for my swap. I'll post a parts list and pictures after my baby is in working order. Quote Link to comment
BEEBANI Posted December 14, 2010 Author Report Share Posted December 14, 2010 hey, I've got 2 sets of upper arms ready to go if anybody's interested. I also have the lower arms that I'm still wanting someone to guinea pig for me. Quote Link to comment
moparvwfreak Posted December 17, 2010 Report Share Posted December 17, 2010 DAMNIT!!!!! why cant i have any money right now..... this blows. i would so snag both uppers and lowers.... Quote Link to comment
Cahoon520 Posted December 17, 2010 Report Share Posted December 17, 2010 Will these work on a 520? Is there a difference between the 520 and 521 suspension? Quote Link to comment
wayno Posted December 18, 2010 Report Share Posted December 18, 2010 Will these work on a 520? Is there a difference between the 520 and 521 suspension? I beleave that 320, 520, and 521 are the same, but I could be wrong, wouldn't be the first time, and won't be the last. wayno Quote Link to comment

BEEBANI Posted January 27, 2011 Author Report Share Posted January 27, 2011 Did someone say Guinea Pig? What have you got for my 521? I still have 1 set of uppers ready to go, and the lowers are still sitting here. They will work on your 521 like a champ! 1 Quote Link to comment
socaldatsun Posted November 5, 2012 Report Share Posted November 5, 2012 So looking into this ball joint swap, well actually was more interested at the adjustable uca. If I do this swap I would have to use the hb calipers? I would really like to keep my z32 setup since I've already put all the time and effort of hunting and installing everything:/ Quote Link to comment
socaldatsun Posted November 5, 2012 Report Share Posted November 5, 2012 Nevermind found it. http://community.ratsun.net/topic/34589-z32-brake-upgrade-for-ball-joint-trucks/page__fromsearch__1 Quote Link to comment
w_datsun_a Posted November 8, 2012 Report Share Posted November 8, 2012 I haven't seen the instructions from Beebani, but the Hardbody shafts will not work. You need shafts from a 78/79 620(disc brakes trucks), or from a 80-85 720 truck. The upper control arm bushings are the same from 78-97, but the arms and shafts changed. I used my 77 shafts and it worked fine...after much fiddling I was able to get the D21 lower control arm working (although I still need to fab a caster rod mount). I have both the UCA and LCA from BEEBANI. Both are beautiful. Quote Link to comment
oldskoolvws Posted November 9, 2012 Report Share Posted November 9, 2012 I have a full setup sitting on the shelf from Beebani as well. Changing routes though. Mine are custom from Bee. They are shortened 2-1/2" (upper and lower) to tuck 8" wheels on bags. I have the uppers, lowers, D21 spindle and NOS 620 upper shafts. Will be selling the whole package shortly if anyone is interested. I'll even throw in a pipe c-notch for the rear already cut and ready to install. Bee's quality is top notch!! Quote Link to comment
BEEBANI Posted September 9, 2013 Author Report Share Posted September 9, 2013 Still making these. Quote Link to comment
GRpufnstuf Posted September 9, 2013 Report Share Posted September 9, 2013 Just got home and found my new UCAs waiting for me. Great quality and fast turn around! Thanks Beenani Quote Link to comment
