hello all. i have a 95 riv, supercharged. i'm attempting to replace my power steering pump with a used pump and im running into some problems. the pump that is on the car presently has the p/s resevoir on the top of the engine on the driver's side. the replacement pump that i almost bought at the junkyard had the resevoir on the p/s pump itself. can i use the pumps that have the res on the pump (after taking the res off, of course). or do i have to find a pump w/o the res? thank you
