This is something we've still been thinking about and talked about today. If we'd caught it sooner, we'd had the machinest drill and tap a hole there for us. We'd rather test and tune this motor on our front motor mount engine test stand as opposed to dropping it in the car when the time comes and going from there. My Dad says he's never had much luck on tapping holes and I'm no subject matter expert on that area. We do have a tap kit and thought about doing a few test runs on a piece of iron. Any advice out there to give us or anything we need to know if and when we do tap for a left, front motor mount?
