Strait or tapered shaft P/S pump shaft?
When I put a March pulley/serp. belt set up of my '69 they needed to know about the pump shaft. When I look at replacement P/S pumps I see no mention of the shaft differences. Down the road I will be upgrading to the 3rd gen. box and would like to put on a new pump at that time. I don't what to have to replace the March serpentine style pulley that I already have.
Is there a year difference or production change that help me determine the correct pump?
