All the '62-'66 slant-6 A-bodies use the same mounts. 2303 and 2304 are the correct aftermarket numbers. Keep an eye on them; most of the mounts available these days are very cheap, but shrivel up and fail quickly 'cause they're made out of compressed cow poo in some part of the world not known for manufacturing anything worth having. If you wind up in that situation, there are super nice poly mounts
discussed here, though I think I'll probably have the maker, Johnny at
Polybushings, make me a set of non-interlock poly mounts for my '62 -- interlock is great for hot-rodded engines, but unnecessary for any kind of near-stock engine and makes more noise and vibration in the car.
Don't neglect the "rear engine mount" (transmission mount). It probably wants attention, too. '62-'72 same.
