Rear control arm adjustment.

Post by LaVelle » Tue Jan 02, 2018 6:49 am

I have a 65' GM a-body that is street/strip.
I'd like to move the I/C back for the rear suspension without going down.
Which would involve moving the lower arm not the upper, if I am understanding things correctly.
Rather than lowering the rear of the arm, I'd like to raise the front.
Does anyone make an adjustable mounting point for the front of the lower control arm?

dont think anyone makes any sort of kit to move the front of the bottom arm up, as without extensive crossmember modifications, there is no where for it to go.

It's been 25+ yrs, but on my '64, iirc, welded a tab on the top of the bracket that allowed me to re-drill the hole through the frame and move the bolt location up 7/8" or so. The car no longer squatted, and the 60 foot time was improved. Iirc, I had to install the bolt in from the inside out, and fish the nut in through the existing access hole.
