Re: Think I got a crappy job done on a weld in rear coil over setup.

You mentioned Alston Chassisworks & Sacramento. Im in Sacramento and I installed the Alston rear coilover kit and rear bar about 20K miles ago on my 65. No problems so far. Parts look well made and the kit was easy to install. Plenty of range for adjustment in height, spring rate, preload, anti-roll, etc. I got the 2-Way adjustable shocks, so theres those combinations to play with too. I think Ive got it all dialed in now for street use.

Dang Mike, I guess we are neighbors. So did you do the weld in kit? Have any pics? How close is your upper shock mount bar to the diff?

It does look tight in there so I'm not sure what they could of done better except for maybe a better lower bracket design. Any thought s?
Wow, that is pretty awful.

Here's a link to the Global west kit shown on a bare frame. It's a bolt in but your welded crossmember should look similar and this video gives you a good view of what it should look like and the shock angles.

Good Information About Rear Coilover Kits For 1964-72 A-bodies - YouTube
Thanks, yea I seen that video. A bolt in kit, and the bar is profiled around the diff which is interesting. Unlike the weld in kits. I'm still hoping to see an install of a proper weld in style kit.

Can you post a part number or link? I didn't see those on Alston's website. Also I'd love to see a pic of where you mount the upper cross bar.

Re: Think I got a crappy job done on a weld in rear coil over setup.

The Alston kit is designed to bolt to existing brackets on a Chevelle rear axle. If your axle is not stock, then their weld-in kit may be necessary. Their resulting shock angle is very close to stock. Keep in mind that the upper cross bar sold by vendors limits space for routing the exhaust. The pipes loop over the axle in the same space.

The last link is a .pdf file for bolt in and weld in kits. You have to scroll down for the weld in pics.

What Greg said.

Tom Terrific or Terrible Tom, depending on the phase of the moon, passing cosmic rays or other factors not fully understood except by my wife.
