Hello guys, trying to help a customer out. Every SB mopar i have ever owned had 2 bolt hole bosses toward the front, and one toward the rear. I'm aware of the 318 to 360 "spacing" difference where some install a spacer. BUT, i have a customer with a 1967 318 that appears to have 2 bolt bosses toward the rear...and only one up front. This must be an early LA thing, as i have never seen it before, and he now has a motor mount where only 2 holes line up. To make it equally confusing, i looked up a 360, pre 72 motor mount, and it only has what appears to be a through bolt...so it'd free swing, other than being confound by the biscuit mount in the k frame. Can someone tell me what i need to have this gent do? just run it with the upper bolts only...so it swings? drill the "missing" hole in his old 318 bracket to get a 3rd bolt in? thank you!!!!! here is what appears to be a 360 motor mount. the old engine is his early 318. the blue one is every other LA i have ever seen.
