Installing rear control arms help
I'm trying to get the control arms installed in the '68. I did this before with the old coils however I believe they are probably shot and that's why I could line them up. I'm having trouble lining the holes up on the upper control arms in particular. I've tried jacking up the rear end, lowering it, putting weight on the frame, using a come along to pull the rear axle inward etc. What do you usually do? These are new coils and I don't have the body on the frame yet. Thanks.

how are they not lined up? Do you need to rotate the pinion up so the ears line up ?
or is it a left right thing? |

It is mainly the passenger side upper. It needs to go a couple millimeters to the 2 o'clock position if you are looking at it straight on. No matter what I've tried it still will not line up. I'm almost just thinking of either dropping the body on it or making some adjustable upper and lowers.

If the coil springs are installed , remove them , get all 4 arms bolted in then install the new coil springs .

Yup, during my frame-off I installed the control arms without the coils. Then, after the control arms are in place, you can install the springs.
The upper diff. attach points were particularly a pain in the derriere'. IIRC, I installed the uppers to the diff. then was able to get the leverage to tweak them into place on the frame. I think I did the uppers, then the lowers, then the springs. I always tackle the worst part of the job first. Good luck Cody. -Matt

Do the uppers first.
I use 2 rqachet straps around the rear to the frame up front and pull the rear until the lowers line up and slide the bolts in. Did 20 cars this way without issue.

I agree with doing only the uppers first and without the coil springs in place. You have to make adjustments on left and right as well as angle of the pinion input up and down.
