GM pumps are set at much higher pressure than the Ford units are. If you tried this with a Ford rack, it would blow the seals rather quickly. Either remove shims to reduce the pressure, or replace with a Ford pump from a compatible system. Check the back of the pump/reservoir for a large hex head plug. This will be the relief valve. It should be threaded in, remove it. Put a pan under it, or your going to have a mess, it will drain the oil from the pump/reservoir. With the relief valve out, see what you need to do to remove the shims. I can only remember seeing three or four shims in a stack on any of the ones I've had apart. Considering the pressure differences, you will likely have to remove them all but the thinnest one. If the steering is lazy, put the next thinnest one back in until you get what you want. If the steering is still over powered with the shims removed, you'll have to go to the Ford pump. It's going to be a messy job, but not that difficult. Best of luck.

I did a GM pump on a mustang rack and I believe I had to add shims to lower the pressure, was a few years back so I may be wrong

I agree with the other fellows on the prressure issue. When I use a GM pump with a Ford MII rack, I use a pressure reducer available from various suppliers.

Ok, since we ended up with two conflicting answers for the same question, I thought it best to clarify. Turns out wrecker55 is absolutely correct, that makes me absolutely wrong.

Thank you wrecker55 for setting that straight. You do add washers to drop the pressure, sorry about that. And it's a flow valve, not a relief valve. Once you remove the high pressure line, and take out the valve, your going to add washers under that little nut. Sniper
