Ya know, I hadnt thought about it until now but I have a 81 Regal with a bad V6 under the hood. Have a replacement 350 coming to drop in there. Will have to check and see if those brackets would work out better.
Didnt look at the Regal parts yet but spent some time to see if I could get the current brackets to work and it looks like they will. Its very close but thinking it will work ok. Had to loosen the fitting on the back of the pump, rotate the HP hose 180 run it through the belt then connect it to the gear box before remounting the pump to the engine. It helped to not have a rad in there yet so I could stand in the engine bay while doing the deed
