Hi Prine, I noticed you really know your stuff & down to earth logic! I was wondering if you could answer a quick question. Just got water pump, carb, etc. went on test drive and popped drivers side motor mount again (just replaced Dec 08 1st night home popped in driveway and almost ran me in the back of the garage. Anyway, when replacing the first time I noticed not flush mounted when engine lowered. Had to go back and loosen everything even metal brackets on block, & holes not lined up perfect. All pulled together after tightening. The previous owners butchered this car. Is there a bracket/mount swap from 1967 Dart 273 commando to 1970 318? Wrong brackets cause mount bushing to pop? Please advise. Thank You!!
