Hi, I have a 1962 261 in my 55 cameo, I used the 60 series front motor mount that was on the engine. My front cross member had the holes for the front mount. Bolt your engine in on the rear mounts and set the engine on the front cross menber. Mark where the studs touch the cross mender and dill you holes. Mine had a rubber mount that went under the cross menber for the front mount.
