Look close at the blade end (distributor end) of the intermediate shaft. The wear is about 5/8 inch from top of blade leaving plenty of room to allow for the drop of the shaft when pressing the gear higher at the other end. The heavy wear at the blade end of the shaft i am confident is due to the extra load of the vac pump.

On a factory set up, if i remeber rite, there is only 3/8 inch clearence between bottom of vac pump and bottom of oil pan. Maybe mill 1/16 inch from the top of the oil pump-to-block mounting flange and ever so slightly dent the bottom of the pan to gain clearence. Mock it up to see.


Denting the bottom of the pan is risky business due to the long draw die process in stamping it. The metal gets VERY thin in unpredictable areas.
