I'm selecting the power steering set-up for my 1937 Buick 4dr Roadmaster. The front suspension will be rear steer like original, but with some parts swapped to add disc brakes and ball joints. Here are the PS options I'm considering:
- 1988 Cavalier Rack & Pinon as described in: http://www.crankshaftcoalition.com/w...inion_steering
- GM 605 Steering Box
- 1995 or earlier GM Van Power Steering Steering Box
I've read the Rack & Pinion will be the most responsive.
1) Can anyone share experience with these options with regards to responsiveness and/or difficulty of install?
2) The Cavalier Rack & Pinion has the attach points for the Tie Rods at the center of the rack (see picture). Does anyone know of other racks from a different vehicle/make that has this arrangement?
3) Is installing a GM 605 difficult and are there instructions available?
Thanks

I saw a rack similar to the cavalier on a race modified 65 mustang. It had an aluminub bar mounted to the 2 center bolts and the tie rod end holes could be drilled to get the right geometry.

Do you know if it was a Ford rack & pinion?
Thanks

It's made in australia, google it and you can see how they did the center pivot rack design to get the right geometry. I have 2 Jag F 40 front suspensions on pallets for the 32 and 29 nash roadster projects and 2 Cavaliar racks and columns. I plan to make them similar to the RRS when I ever get to the build. Tie rod pivots. can be done to get No bump steer. Some suspensions have a wee bit of bump steer to compensate for chassis lean. tire camber change on turns, but minimum bump. on straight ahead bumps.

Thanks for the info.
Interesting that no US aftermarket kits are avail with this set-up.
