E-bay has the front engine mount plate with the foot that allows mounting the later Chevy engines which had side engine mounts in the older 216 front engine mount location. (I bought two a while back have not installed them yet so I cannot verify that they work on CMPs but they look like they will.) For the price worth looking at says used but the two I got were cosmoline covered still in the original box . (Normal no relationship to the seller)
