I'm cleaning up the shop and came across a box of what I think is truck motor mounts, or engine brackets. I think I have both early and later truck mounts, mostly big block but the black set is marked 360. Just thought I'd double check here before I put them up for sale. Are the straight ones the later 2wd truck mounts? I think the ones with the extra kickout bend came from an earlier truck, maybe a 1970?
