There is only one exception - I don't know the model designation, but it's a big truck with a hood that looks similar to the pickup version, but it is substantially shorter from the nose to the windshield.
Other than that, any 60-66 Chevy or GMC hood will interchange so long as originality isn't important. You just need the hood latch that goes with the hood. On the 60-62 style the release lever points down and is accessed in the gap between the hood and the radiator support. On the 63-66 version the release lever is accessed through the rectangular hole on the front of the driver side.
