Thank you el Diablo.  I agree.  Once I get all the bearings replaced, I'm going to need somebody to go through my motor and tyranny to replace ANY wear and tear items, minus the gears.  I have 2 230E engines and I'm using one for parts and the other to get rebuilt.    As far as aftermarket parts for the 230's, I can't find a single aftermarket part for my 87'... but I have found aftermarket parts for the later models.  Such as supertrapp exhaust, and tie rods.
