**Pro Street Ladder Bars???**

Ladder bars act as a massive anti roll bar...not allowing articulation of the rearend housing. The bushings help some, but I still don't think it's the best idea. If you seldom drive the car, sure. If you drive quite a bit, look into building a 4 link setup that is real short in the front. Hell, the upper and lower links can be 2" apart at the front, but as long as they are using seperate bolts, the rearend can move some.
There are some companies that sell these type of setups for the Chevys...Martz chassis is one I think. It may give you some ideas.
