what about the oil passage in the back bearing or is it the same??
I never looked. But, do recall the front screw.

You could just tap the block all the way down and put 1 long screw from the outside. How long would that screw have to be??

I've always had the machine shop do the bearing while the block was in there. Or, just left it in. Might save myself 30 bucks next time.
