no info on the subject at hand but I just had an issue with the front gasket for the half moon (under the tcover) on a speedway mtrs new pan so be sure & mockup/check fitment as needed before you breakout the cement. the 2 different sized holes (on each end) in the pan for the nubs to be pulled into need slight enlargeing with a drill (no big deal) but another thing to check if needed in your deal. If the 1 piece dont fit or another 1 piece doesn't fit I would go with regular gaskets (& be sure to check pan bolt hole flatness). I dont care for cork but not sure what is out there. EDIT & on the cork you may need to cut the long length into several sections for the bolt holes to line up. MORE EDIT the pump to tcover gasket fits better flipped one way, mockup/flip it dry on the pump & you will see the best way, that it covers quite a bit better.
