oldsklminitrk Posted December 1, 2009 Report Share Posted December 1, 2009 Well Fatt stripes(Matt) and Datsme(Allison) dropped off Allison's frame tonight to me to get started on it.There gonna help in the build but a lot of the fabrication I will be doing.Its probably gonna get a L20B engine upgrade with a 4 speed.Were gonna ditch the king pins and use a setup off of the 78 620 parts truck I used to have.

datzenmike Posted December 1, 2009 Report Share Posted December 1, 2009 (edited) Now's the time for fitting the motor and tranny. If you have a '78 why not graft the front frame from it on just behind the rear mounts for the torsion bars. This would give you the better ball joint steering, front disc, L motor mounts and tranny mount for the long 4 or 5 spd. in one go. Edited December 1, 2009 by datzenmike Quote Link to comment

Sudo Posted December 2, 2009 Report Share Posted December 2, 2009 this is sweet. I have a 67 520 in the garage AND a 78 620 parts truck with a L20B in it in the backyard... I may just copy this build instead. SO what about DatzenMike's suggestion? :unsure: I think its brilliant. If you don't I might- what are the drawbacks? If you do, I definitely will! :) Quote Link to comment

Now's the time for fitting the motor and tranny. If you have a '78 why not graft the front frame from it on just behind the rear mounts for the torsion bars. This would give you the better ball joint steering, front disc, L motor mounts and tranny mount for the long 4 or 5 spd. in one go. Yeah Im looking at doing that or Im in the thought of just building a whole new frame from scratch. Quote Link to comment

Charlie69 Posted December 3, 2009 Report Share Posted December 3, 2009 The only drawback I can see is the frame numbers, needed if title is transferered to a different state. The frame # on the 620 frame I beleive is on the top of the right hand frame rail just in front of the shock tower. The 520 frame number is ont the top of the right hand frame rail just behind the shock tower. When a vehicle is brought to AZ from another state for title & registration it has to goe through an Arizona Department of Motor Vehicle inspection. This inspection has to have 2 of the 3 original numbers match, either 2 of the Body# (VIN), the Chassis #(frame) and or the Engine # (Serial). If 2 do not match no title or registration in AZ. Not sure how other states handle this. This is the main reason I did not use a 1980 720 frame I have. Quote Link to comment

This is the main reason I did not use a 1980 720 frame I have. not so much an issue if the stock numbers are left in tact and moved to the new graft it is not vin forging considering the fact that your just replacing part of the frame so grind down the 620 numbers and keep the 521 numbers in tact problem solved Quote Link to comment
oldsklminitrk Posted December 6, 2009 Author Report Share Posted December 6, 2009 (edited) Ok so......all Ideas out the window I decided to atempt something else....I took the entire front suspension off of the 520 and swapped the king pins and put the 620 disc spindles on and it all bolted right up.Even the tie rod ends lined up....so I retained the original frame but upgraded everything to the newer style stuff..... So basically here are a few pics of one side mocked up and seeing if everything fit and it brought lower to the ground. Edited December 7, 2009 by oldsklminitrk Quote Link to comment
Charlie69 Posted December 7, 2009 Report Share Posted December 7, 2009 Looking good oldsklminitrk! Just curious, Is there any difference in the in the tortion bars? Is so what? Quote Link to comment
oldsklminitrk Posted December 7, 2009 Author Report Share Posted December 7, 2009 Looking good oldsklminitrk! Just curious, Is there any difference in the in the tortion bars? Is so what? Honestly I dunno.....I didnt try that part since they had to come out to be bagged. Quote Link to comment
Pacific coast Datsun Posted December 8, 2009 Report Share Posted December 8, 2009 Very kool that it all swapped over. Quote Link to comment

slam_dat_sun Posted December 8, 2009 Report Share Posted December 8, 2009 Finally I can see the pictures ! Quote Link to comment
Charlie69 Posted December 8, 2009 Report Share Posted December 8, 2009 Honestly I dunno.....I didnt try that part since they had to come out to be bagged. I beleive the 620 torsion bars are longer like the 720. Keep up the good work. Quote Link to comment
oldsklminitrk Posted December 9, 2009 Author Report Share Posted December 9, 2009 Well I got the front all laid out tonight and I had to pie cut the upper control arms as I suspected but it all lined up pretty good. Quote Link to comment
mklotz70 Posted December 9, 2009 Report Share Posted December 9, 2009 Did you pie cut the UCA's because of ball joint bind or because of the positive caster that you get with this setup? Quote Link to comment
nukeday Posted December 9, 2009 Report Share Posted December 9, 2009 (edited) Let me get this right, you swapped 620 upper and lower control arms and the ball joint spindle right into the 521?! For a stock setup the obvious question is the torsion bars. Do you have any plans to use them at all? Any more photos of the actual swap in progress? Edited December 9, 2009 by nukeday Quote Link to comment
Madness Posted December 9, 2009 Report Share Posted December 9, 2009 Wait. What? Everyone told me it would mess up the front suspension geometry.... Sadly, I'm pretty sure everyone is right. :mellow: Quote Link to comment
