I got mine from TPiS. It fits well and allowed me to retain my original belt.

Upon further review, the unit that Doug Rippie sells is the TPiS unit.

I was looking at some of these and then pulled my pump apart, removed the fins inside and replaced the rear bearing. I wont get the advantage of a smaller idler pulley but it was easy, cheap and still looks stock.

I did this as well, my only issue with doing this is that the valve cover is still hard to get off with the pump in the way. It would be nice if there was a way to cut some of it off.

I made my own and posted step by step pics here but heard about it from one of the supporting vendors, they were upset that I built mine for about 1/10 of their cost. All I can say is that if you have the ability, get yourself some 3/8" flat stock, some 3/8 steel tubing, a tape measure, and a hacksaw. In my case I welded the pieces together but they can also be bolted together.

Couple of pics of one I made.




I had access to a lathe, but the spacers could be made without one. Here is some info on mine.

Nice work If I could have made one look that good I may have made a bracket rather than Gut my Pump. You could sell those I am sure, the ones I looked at from the suppliers looked ok for a race car but that is about it. I probably a fended a few race car owners now

Wow, Dan, nice work! Now that one is worth the money some suppliers are asking for the flat bar, plastic pulley crappy looking deals. At least the TPiS has a little styling with the brackets. Still have the plastic pulley tho. Anyone have a long term report on how well the plastic pullies hold out? Looks like the weak link.
