So my 68 RR came with AC and the book calls for a six vane water pump. If I had the original I would get it rebuilt but I don’t have it. All the parts houses seem to have are standard eight vane. I am going back O.E. so I really would like to have the pump style the factory said it needed. Do any of y’all have a line on a place to get them? Or even an original pump? Thanks in advance.
