Correct me if I am wrong, but aren't the Hooker mounts a front engine mount style? If you are looking for a stock side engine mount these are different. The ones Bob sells are made from one half of a H-body mount and the other half off a mid 60's truck I believe. As far as getting stock side engine mounts from a parts store, forget it, you are not going to get those.
