Measuring ride height

The fenders are not necessarily the same height off the frame, so that's not a real good point to use.

As long as the frame is not sitting on the LCA bumper there is no need to loosen the nut. The LCA rotates around the torsion bar socket.[/QUOTE

Well Jim,
Mopars dont have frames, so thats not a real good point to use either.
Unibody cars, remember ?

Ive studied and worked on these cars for many years. The technique of loosening the 2 lower control arm nuts when making any torsion bar adjustment, is a practice I will continue to use. Im confident in my ability of building some pretty nice cars. Go ahead and get out your levels, calipers, plumb bobs, elastic strings, 2x4s, bricks, land surveyor, and whatever else you think you need. And have at it. :)
