    I am still working on 1 of my many projects, my 54 Pontiac. it is not too far off. 400 poncho engine, 400 turbo already installed, rear end needs changed yet, have disc brakes for it, but steering is still the issue. I had to remove the original steering box do to clearance issues. thought I would put a rack and pinion in. it is a rear steer. 1 has anybody done this??? 2 even better how about flipping to front steer??? is it possible? 3. vega box??? I am not real interested in the cavalier rack though. any ideas at all, pics please!!!
    thanks

    I do have a cavalier rack, but it seems it does not work on a Pontiac as with chevy. the fat man or butches brackets directions are no where near correct for Pontiac frame width with the cav rack. they look a little weak as well. if anybody has made any please post some pics.

    If you change to front steer, with the tie rod in front of the wheel center line, you need to move the location of the tie rod ends out past the kingpin.

    If you use rack, you also have to get the inner tie rod ends to be mostly on the plane of the inner control arm pivot points, as well as having the effective tie rod parallel to the lower control arm...all of this is to prevent bump steer. And its usually not easy to find a rack with the correct length, and a place to put it that meets these requirements.

    Another solution might be to go for the modern concept of a g***er, and put a straight axle in it, with a front steer Vega box.

    I probably would have installed the engine with the original steering still in place. There is usually a way to do it, although it can be difficult on some cars that came with a straight engine.
