maximo Posted February 3, 2010 Report Share Posted February 3, 2010 "RADIUS RODS" IS THERE OTHER NAME FOR IT?? I LOOKED AT THE REPAIR MANUAL AND I COULD NOT FIND A PART WITH THAT NAME UNDER THE SUSPENSION SECTIONS. :( Quote Link to comment
Guest DatsuNoob Posted February 26, 2010 Report Share Posted February 26, 2010 Sorry, I guess the proper name for the part I'm trying to describe is actually "upper control arm shaft link". I still dont know why the hell you cant just use the 620 ones with Beebani's A-arms. Quote Link to comment

I still dont know why the hell you cant just use the 620 ones with Beebani's A-arms. Noob, you should be able to use the shaft from a 78/79 620. I beleive they are the same as the ones from a 720, i have used both 620 and 720 in my truck(1976 frame). Quote Link to comment

Guest DatsuNoob Posted March 1, 2010 Report Share Posted March 1, 2010 Why the Lolz? At first glance I didnt see why the kingpin ones wouldnt fit in Bee's UCA's. I didnt measure though, it just made sense to try and use existing shit to mount up my arms if the spacing was the same. I'll be on the lookout for a pair from a late 620 or early 720, whatever.

krecs Posted March 6, 2010 Report Share Posted March 6, 2010 So I'm starting this on my truck real soon, got mostly all the stuff except for the UCA pivot rods. I've found out for myself the hard way that HB UCA's and pivot rods will not work out. Width difference of the mounting holes of the UCA pivots are different spacing. early ones are 19mm and later ones are 22? 24mm cant remember. Anyway, my question is which UCA pivot rod will match the factory holes(spacing and hole size) in the frame of a 620 and still have the same length as what's in there now? hey if you guys need those parts i just changed them out of my 620 and have them for sale upper and lower arms with new bolt joints, calipers, spindles and rotors i changed back to the original parts to modified to use bigger rotors. thanks jc Quote Link to comment
datzenmike Posted March 6, 2010 Report Share Posted March 6, 2010 The spindle or knuckle is the same part number from '78 to Oct. '82. This is when the 720 up graded to vented rotors and larger calipers. The spindle from 11 '82 to 10 '85 were the same. The D-21 11 '85 and up used a different number but I think would fit the earlier late 720. Quote Link to comment

dew Posted May 21, 2020 Report Share Posted May 21, 2020 hate to resurrect another corpse but.....for easy 4 or 5 lug swap I and a {circle track racer} guy I know turned down 720 spindles on a lathe, and mounted '84 300zx calipers, rotors, hubs. just shim out the mounting bolts with (4?) washers. Early SAE brake lines must be changed to metric. Works good. Easy swap over to later 5 lug too (sorry 240sx guys). So 6 lug, or 5 lug, or 4 lug is easy on 720 spindles. If you can find solid flat back hubs, a 4x4.5 hub can be redrilled to 6x5.5 using 2 of the holes as guides. And for 4 lug rear triangulated 4 link use '84 200sx, Just needs 2" channel (2.5? sorry, going from memory) welded to frame top and clip the outside bushing a bit on lca, (properly should move lca inboard a bit at axel side), and drill out LCA bushing on frame side to 5/8" Maybe get adjustable UCA so you can dial in the pinion angle easily. Axel is few inches wider though. A little later yrs you get rear disc to boot.Though you probably want to get softer UCA bushings on that light a rig to allow it to work best. I would think it would make a nice wide body set up using the longer LCA. Watch your ackerman...... Quote Link to comment
