55-59 truck engines had front mounts, cars of that era had side mounts. Not sure about 60-62 truck mounting as they were different. However, car engines can be used in trucks and vice versa as the mount issue can be overcome. I installed a 60 car engine in a 59 truck by drilling the front plate and the frame and installing a mount between them.
