C1 (56-62)  Corvette's did not have the conventional SBC GEN 1 motor mount. They used an engine brace across the front of the block. There is no drop in motor mount solution unless you get an aftermarket frame. Check out our Universal Motor Mount Solutions for a weld kit!  Getting an aftermarket steering rack makes the swap much easier.
