My new motor mounts came in last week, and I noticed they're of different thickness. One of the is roughly 1/3" thinner than the other. They are the early '65 type that mount on the 45 degree bracket. I can either send these back and wait another few weeks for my local place to get a new set in (these were the last) or I can try these. I asked a few local guys and they didn't seem to think that the small difference in thickness would be an issue. I'd attatch a pic, but the only one I have is gigantic and not posted on the web anywhere... Opinions? Thanks in advance as always.
