I am getting ready to change out my HPOP. I purchased a reman and it came with a pump gasket, but I think I need another gasket for the oil reservoir. I read on here somewhere that the 99.5+ gasket will not work on the early 99's. Does anyone have a part number for the early 99 reservior gasket? Is that the correct name for the gasket I need? Do any of our sponsers carry it?
