Motor Mount modifications for 340/360 into Early A
What year are those brackets for? We are talking about the "early" A bodies. 1964 to 1966. Those pictures are not for a 64-66 conversion. 67 up are different brackets and insulators.
Another potential hiccup is the rear bolt holes on the drivers mount. Some of the 318 bracket have three bolt holes in them not 4. If the bracket has three holes it likely won't line up with the rear mount lug on a 340-360. I have done this to the mounts to get them to work.
Left is the modified, right is the 318 mount.
