Polluted Posted April 9, 2020 Report Share Posted April 9, 2020 Hey. I bought a 620 last summer and had an awesome time ripping around in it. This winter I've been messing around with a few things and I finally decided to take a look at the previous owner's suspension modifications. He did a ball joint and disc brake conversion on the front end. The way he did the ball joint conversion is a little unusual. He hacked up an upper control arm off a 720, then welded in an extra inch or so from a second control arm so it would reach the spindle. He also shimmed the whole thing where it bolts on to keep it from fouling on the upper shock mount. Pictures of the whole setup below.... https://imgur.com/a/HjeeDr3 https://imgur.com/a/oJMUTMm Anyway, my question is would it be possible to order some Beebani uppers and mounts off Ebay and do the coilover swap given the modifications the previous owner already did? Would the Beebani upper control arm work with the spindle my truck has on it now? Is there any other reason it might not work with the parts I have now? Quote Link to comment
datzenmike Posted April 9, 2020 Report Share Posted April 9, 2020 If this works leave it. Looks like '83 and up 720 or early Hardbody brakes. What's the point of switching to coils? Quote Link to comment
Stoffregen Motorsports Posted April 9, 2020 Report Share Posted April 9, 2020 If the work was done to a decent standard and the alignment is good, leave it. Coils are good, but nothing wrong with torsion bars either. Quote Link to comment
Crashtd420 Posted April 9, 2020 Report Share Posted April 9, 2020 It might be me or the angle of the picture but you might want to check the length of the bolts holding those upper control arms on..... To me I can see the threads of the bolt to the right of the shock but I don't see a bolt coming all the way through on the left... it looks like you can see the inside of the threaded part of the frame....

Polluted Posted April 9, 2020 Author Report Share Posted April 9, 2020 I see what you mean Crash. I think the guy who fabricated this setup has something welded between the mount and where those shims are that the bolts are actually threaded into, but I'll take a better look in behind to make sure it's all safe. As for why I would switch to coils, the truck was actually beautifully restored and sorted when I bought it, but I can only drive it 4 months out of the year where I live, so I'm going to tackle one or two big projects every winter for no other reason than I can. 1 Quote Link to comment
datzenmike Posted April 9, 2020 Report Share Posted April 9, 2020 That's not a reason. If you think coils 'feel' better or your more familiar with them say so. I grew up with late 60's and '70 Dodges and they were all torsion bar. They work perfectly but if I had a ford or chev I wouldn't convert it. Quote Link to comment

Crashtd420 Posted April 9, 2020 Report Share Posted April 9, 2020 I cant say I would spend the money on the coilovers if only being able to drive it for 4 month... is that daily driving for 4 month or the length of potential time you can drive it... If nothing more than you have time and money then go for it.... Quote Link to comment
Bleach Posted April 10, 2020 Report Share Posted April 10, 2020 They did a proper conversion. The welds look good. Quote Link to comment
