Hey guys, I haven't posted here in quite a long time, but do read at least every couple days. But now I have a few questions. I am doing an in frame overhaul in my TO 35. Most urgent at the moment concerns the oil pump cover (flat plate). My buddy took it apart and did not pay close attention. The inside of this cover/plate has a machined area on the inside and we need to know if has to be positioned to a certain side in the pump. If so, how can we determine which way it goes?...........Second question is whether there is a front/ back to the new pistons. I have complete sleeve kits and have installed the new pistons on the re bushed rods. I could not see any marking to designate front...true? Thanks for any input ! Ron
