Reply to "Slotting Engine Mount Pedestal Holes - Anyone done it?"

Bending the steel ZF frame-ear(s) is by far the quickest, least invasive and most simple way to tweek the powertrain mounting position: no welders, drilling, cutting etc.  Incidentally, the rubber lip in the rear of the mount bushings is only there to prevent squeeks; if you have none, there's really no problem with leaving things as they are. Ear welding on the subframe was not micro-precise in Italy.

IMHO, most owners are interested in moving things backward for clearance. Shifting the powertrain forward very far risks driving the distributor cap and water pump pulley into the firewall or the steel access door. Adding to this thread, it's far easier to fiddle with the aluminum ZF mounts and the tranny itself if you remove the three studs holding each casting to the ZF and replace them with proper length metric bolts. In this case, the protruding studs are more difficult to work around than bolts, even though the threads go into an aluminum gear case.
