Default Rack and Pinion conversion

Ive seen a Number of threads on this and the ones linked in the Technical Recource Page but Iím donít see where anyone lists any specific pat number of a rack and steering colum connection parts they used. I see a mention about using a K car rack and a Taurus, but no details. Does anybody have details?

Iím also wondering about the pump, Iíve read where the OEM pump will not have enough pressure, but can I use it and if steering is to hard replace it? I have the newer style one piece pump, like in rye mustang, does it also have too little pressure? Is there a replacement pump tgat works well?

I welcome all input on this subject.

Boris, I got your email and I tried to reply but your email address kept failing. Make sure your email address is correct.

CLICK HERE for answers to your rack and pinion questions.

I did NOT use any K-car parts in mine although I would imagine it's possible. Go through the linked thread. I explained my conversion in detail. - Dave

I am working on this conversion among many other things. It is a big project, but if you get you take time and think it through nothing is really that difficult. One thing that I did was use some small pieces of scrap and tack weld them between the engine crossmember and tie rods so I could keep the steering geometry as close as possible.
To me the hardest part is holding the new rack up so you can mock up brackets. The brackets simple L shaped, I welded mine out of metal I had laying around but could have had a Lot bent and only had to drill holes for the mount.

I see a few months have passed since your last post. I am planning on doing the same thing (rack and pinion) so would be interested to see if you have made progress since May.


Thanks, Mike

So far I have remade the mount brackets to shift the rack over so the tire did not hit it and fabricated a mount for the new power steering pump.
Right now I am waiting for the new steering column to show up so I can get everything connected.

Were you the guy who had adopted the TBird steering wheel to the aftermarket column? I have been looking at those too, but with column shifter and key on dash.

Which wheel was hitting the (Cavalier?) rack? What motor do you have? Got any pics of current version of pieces fabricated so far?

Thanks, Mike

Default Another Corsica rack

Back in 2000 I put a Corsica rack in my wife's 60 hardtop. We had the car since 1993 and the steering was a mess. (Leaks, slop). I saw that rack with the movable center and no integral tierods while walking thru my favorite junkyard and thot it looked interesting. I removed everything from the column to center link on the 60 and "just started". Derbird mentioned having trouble holding up the rack to mock-up the mounts. So did I. I finally wired (you know, bailing wire) it up to anything I could find on the firewall or the engine. I put pieces of wood wherever I wanted space from other parts, like the oil pan or Bell housing cover. Then I was able to make cardboard mount patterns up to the steering box and idler arm holes. The rack sat right where the center link was. Welding the mounts was the easy part.
Tie Rods: I made a 8 inch long 1x1 solid bar with four holes in it to hook up the original tbitd tie rods. Two center holes to match the moving member in the rack and the two outer holes at Ford original width were tapered holes, to take the tie rods.

The column was a real treat. I cut off the steering box and used the shaft. I made an end cap that held a bearing. I made a floor mount to support the column. Noticing that there was going to be a pretty sharp angle needed to reach the rack, I also shortened the column (and shift tube, etc.) to allow for a lesser angle. This brought the shift lever at the bottom of the column inside the car. So an aftermarket shift cable runs outside from down there. Mike S.

Default Corsica rack

Just to finish up: I used two Borgensen joints and a connecting shaft to hook up the column to the rack. I had to re-route my left side exhaust header pipe. You may not need to, cuz my pipes are for a 61-63 Bird, (don't ask me why) which slope differently and have a short crossover farther back. I used my original pump, which groaned when you grind the tires at a standstill, but drove quiet. I had the pressure hose made locally. I probanly left something out, so ask anything. I might even remember what else i went thru. Hope this gives you some idea of how one guy did a rack. Mike S.

I am going to do this with the engine and trans out for the most part and using a 460, with 429 PI exhaust manifolds - if they fit.

Those have a rear dump both sides so I don't anticipate any clearance issue by the gearbox area that usually is the tight spot.
Could run into one at upper A arms though...

If you are using the older FE pump and it mostly works, wonder if a 71-73 Lincoln 460 pump would have a little more pressure and maybe save me the work of making brackets for a more modern pump..

Maybe that pump doesn't put out any more than the 1960 era pumps though, IDK.. Somebody here probably does know though..

I noticed the u-joint angles were pretty tight on some pics I have seen and that Borgeson tells you not to go past 30 degrees, but you can probably get by with a little more than that.

Was thinking that if I cut my column real close to the firewall it might help that issue, but you went even further back than I was thinking. Know what length your steering column ended up being?

Have been looking at aftermarket columns too and they are available in different lengths, with a column shifter and with key on dash, where I prefer it.

Switching to a cable shift is another idea that might help with clearance issues too. Never would have thought of having it inside the car. Creative..

Know roughly what year Corsica, so I can compare the racks?

Do you have pics of any of the work or parts you completed?

Thanks, Mike
