My ‘67 Barracuda convertible, Formula S, 273, PS, PB, automatic had its engine wiped out before I got it. The PO installed a ‘68 318 and did a lot of questionable mechanical, electrical and body work. I am in the process of rebuilding the car and undoing hooptie quality work. Which brings up all sorts of stuff I have never dealt with. These are the motor mounts that held the current engine, with no two bolts being the same. Are they correct for this use and do I buy new mounts for a 273 or a 318?
