Am I missing a part? 58 235---can't get the dizzy to go all the way down. It is indexing the oil pump and cam. I've tried the one that came out plus a second mallory that I have. Same problem. Looks like it's about 1/4 inch shy of sitting on the block.It's a new pump that had the same M45 number on the housing but I did not check them side by side and yes the pan is on and all buttoned up
