awhile back a guy posted where he mocked up the seal holder/seal halves without the crank in there & moved the holder/seal halves slightly fore/aft till the seal halves were aligned dead on then scribed 2 lines on each end of the cap on top & on over sideways to the block then he aligned everything back to that point when together. (he was haveing a seal leak issue).
