Early A mounts

Parts cattledogs at auto parts stores are full of errors regarding ancient cars like ours, and engine mounts are an error "hot spot". Fact is, all '62(!) to '66 A-body Slant-6 cars take the same left,right, and rear (trans) mounts. The (very) best ones are these, but Johnny @ Polybushings says they're "out of stock for now"; you might want to contact him and see when they're going to be available again. The good poly rear/trans mount is the item at the top of this page.

Failing that, shop carefully; much of what's available through parts stores is compressed cow poo from India or compressed girl-children from China. About the best you can do on the general open market: left one is this one, the right one is this one, and the rear one is this one.
