Have this complete kit brand new from years ago (1 3/8 sway bars,springs,poly bushings, rear lower controll arms, 78 camaro tall spindle etc.) Has anybody used this kit or still using.Would like to know the pros and cons of installing this on my 454- '69 Chevelle post.Came with 480lbs rate SB springs and I assume that will have to change to BB but dont know what to get to compliment the package.

What exactly does the rear arm kit consist of? Do a search in this subcategory for "poly bushings".

All poly bushings front and rear.Rear gusseted lower control arms, 1 3/8" sway bars front + rear,480lbs fr springs 1 1/2" drop,rear is 156lbs./inch w/ 1/2" drop, all new ball joints and outer tie rod ends to fit GM tall spindle,Moog offset shafts,Koni fully adj. shocks,calipers and 11" rotors.

Don't run those rear arms, do the previously mentioned search for all you ever wanted to know about using poly bushings in the rear suspension.
