MR2 Rack in Pantera

Funny you should mention that, since I have that whole rig in my garage, waiting for Spring. The tapered tierod ends will fit the Pantera steering arms and the reservoir is remote-mounted to the electric pump. There are two brain-boxes for the speed control to vary the amount of assist. This will be the difficult part. The mount to the Pantera body will also be a challenge since the power rack is about half the length of the Pantera's Cam-Gears rack. FYI, without variable assist, most/all the power steering Panteras are radically over-boosted, making them feel totally 'dead' while driving. Since the biggest problem is driving the pump, I'd suggest you use the stock 4.6-liter pump, string your lines & use the Mustang 2 rack. It's a little slower ratio, so you might continue to look around for a better power rack. Note- this adaption is difficult,and IMHO not needed unless you are physically challenged, running 11" wide front tires plus doing mostly city driving, parallel parking etc. This is the intent of my future adaption incidently.

Have you looked into using the power steering line off a 90s t-bird. My sc t-bird powersteering is variable controlled through alittle valve in the line.. I believe its sensative to loads so you wont get dead feel while driving around on the highway. Maybe cheaper alternative to running the computer system. Also could you adapt the power pump from the mr-2 to a pinto rack. By playing with the voltage you may get the desire assist without over powering the steering.

On side note which of the hydraulic throwout bearings work with the zf? toploader? t-5? chevy stuff? PAW sells the bearing for several trannys.

Never looked at the T-bird. What controls the valve? If its electronic, you're back to square 1. Some guys have had luck in adapting mismatched parts by putting a needle valve in the pressure line to reduce pressure, but that seems to shorten pump/seal life.
FYI- these are racing units so none of the non-vendor hydraulic throwouts work on a ZF without considerable lathe work. The vendors either make an adjustable height mount that fits inside a commercial unit or adapt a whole custom nose section to allow it to fit. Installed free clearance is THE big thing. Unless the system is rigid and has around 1/8" of free play when hot, hydraulic throwout seal life will be measured in hours.

The power steering line has the valve built into it. I'm certain that the car has variable control, you can tell by driving it. The powersteering has no wiring at all so the control must be a valve. When I inspected the powersteering line to the rack I notice alittle metal cylinder running inline with the hose. The normal powersteering lines for mustangs and such are identical to the t-bird except for this cylinder. I had one sc t-bird with a bad valve, the steering alternated from normal to feather lightand back when taking long turns. My new sc does not do this.
