Re: bump steer

the top picture of this kit looks like it will attempt to reduce bump steer to my eye, axle moves forward on bumps and steers right, pitman arc will counter that:

that looks like a saginaw box from c10 or similar with the pitman arm reclocked

57tailgater posted a version of that in post 9. I don't think that example could be a squarebody steering box though as GM light truck boxes from IRS years are all front steer. This setup might not work with a v8, it takes up some space between the rails



Another option to consider is a center steer rack and pinion mounted to the frame, not the axle. Having the long tierods will reduce bump steer but not eliminate it.

here is a list of center steer racks I also lifted from a mustang forum:
Front Steer
Dodge Intrepid
Chrysler Concord
Eagle Vision


Rear Steer (what you'd need for a stock axle AD)
Saab 9000/Early 9-3
Honda civic
Cavalier


for front steer Dodge intrepid is one I have had my eye on, but the cavalier is very similar from what I have seen. (not sure all years cavalier use center steer)

Stole those pictures from somewhere, so I can't claim them as accurate
