I found a source for cheep 1” rear sway bars. I can get used ’73-’77 Malibu rear sway bars for $50. for anyone interested here is how I made it work on my 1970 chevelle. I boxed the lower control arms and drilled drain holes for any water to escape. I also welded (4) steel Ύ” OD x ½” ID x 2-3/4” long tubes to the control arms, 2 on each side. The first one is 13” back from the center of the front bushing; the second is 5 more inches back. The rolled lip must be ground away to allow the tube to lay flat against the control arm’s side. This was done to accommodate the ’73-’77 1-3/8” rear sway bar. ’73-’77 control arms mounted on the bottom and the ’68 – ’72 mounted on the inside face of the control arms. The bottom-mounted bars are better because they don’t require shims to eliminate sideward bushing preload. The sway bar has slots that provide all necessary adjustments.

no takers of comments?
these 1" bars are commonly found on police caprices. i have access to a whole pile of them.

Hey Pete its another good idea that you have there. Maybe once I get the car rolling again I will try to incorporate that into my suspension design. Although i have been playing with the idea of a GW type rear suspension. By then though I am sure I will change my mind a million times!!! graemlins/clonk.gif
