The seal on my stock style PS pump is leaking (again) and I'm looking for my options to replace it. The pump is on a 1985 Monte Carlo SS with a SBC, a press on style v-belt (March Underdrive) pulley and in the stock mounting location. I'm pretty sure I'd like to stay with a pump that will fit in the stock mounting location. Also pretty certain the steering box is a 12:1 ratio box (F41 option) and it's in good shape still.
I'm autocrossing regularly and also have a power steering fluid cooler that I'll plumb in the return line when I install the new pump.
So is there an upgrade aftermarket pump that will bolt into my stock location or are my choices just limited to stock replacement type pumps? and if so, has anyone had better luck with one brand standing up to abuse a bit better than say another?
I guess I'd consider a pump with a remote reservoir if I was certain it would bolt in place and I wouldn't have any pulley issues with the rest of my system.
So...any good suggestions?

You could just change the seal, heat probably damaged it. A cooler is a great addition. I wouldn't add a remote tank to your stock pump. The reservoir is removed, then the pump has to be drilled & threaded in a thin area of the casting, so the fitting could have leak issues. There have been plenty done this way, but it's just not ideal.
You could go to a late model pump, but they are no better. Sweet makes late model pump kits.

So you just replace the two O-rings inside the pump housing, the O-Ring that seals the reservoir to the pump, and the 3 O-rings for the hose and bolt locations? That's it?
How come I've always just replaced pumps instead of fixing them in the past?
