Trying to put together my 61x/62t engine, following the how to in the faq section and the 62t matched cases fit together fine without a driveshaft in them but when i put the driveshaft in it seems like there is a high spot in the middle as if the center bearings are too thick, if one end of the case is pressed together there is a gap on the other of a hair less then 1/8th inch, what is going on here. the bearings and center divider are all aligned with their locking holes and all surfaces were clean.
