on my 1970 350 engine I am replacing pan gasket. From a search of prior posts I am told that FelPro makes a one piece gasket, pn OS34509T. However another post indicated that this may have the rounded out part for the dipstick on both side of the gasket. I don't want that. My dipstick is on drivers side. Has anyone found a one piece that has the dipstick moulding on the drivers side only, so it looks like a factory fit?
