[71rsz28]

I have a 71 z28 that seams to over steer with very little road feel that is aslo currently leaking. I would like to replace the unit with a unit with better qualities.
My current box has 4 bolt holes on the unit but is only fastened by 3 bolts in the frame rail ( 1 upper forward & 2 on bottom. I checked the number on the top of the housing and it has 5691676 with a search i could not find this part number. I also checked the number on the front seal which is held in by a ring clip that number was 7800715 which seams to come up as a gmc 96 part??
Can I use my existing pump?
What ratio box should i be looking for?
What would be a good manufacturer?

Thanks for all the help.

Try borgeson.com they carry new stering boxes and can get you a match for most domestic cars..including options for quicker ratios..You probably have a saginaw box and your existing pump and plumbing should be fine provided those pieces are in good condition..

There's a trick that if you take the guts from an '88-'90 Firebird WS-6 or '88-'91 Z-28 box and reassemble your box with those guts you'll get 12:1. I know a friend that did it and he loves it. I have all the parts and am getting ready to do it myself. I'll ask him what the exact serial # is you need and how it's done.

huh... or you could just bolt the box on to the frame and drive it. Why make it hard on your selfs?
