When I was cleaning up and painting this engine, I missed the fact that the front alternator bracket mounting hole has a 3/8-16 bolt broken off in it about 3/16” below flush. What to do?
1) Drill and tap the old bolt for a 5/16 bolt. Use a left hand drill bit in the event it is willing to catch and back out.
2) Remove it with an easy out, hoping not to break off break off the easy out in the hole.
3) Being so close to the new pan gasket, heat-related techniques are undesirable.
4) Buy a bracket that mounts to the front of the block. Davispeedequip sells them on eBay, part number 10022 or 10022AA. This looks like a good plan B if others fail. Does anyone have experience with these brackets?
