1954 GMC swap

[Flysocal]

Let's say a guy wanted to switch his 54 Chevy front sheet metal to GMC. Hypothetically speaking will I need a 54 GMC hood, front fenders and grill? Is that all? Or is the inner fenders, hood latch, core support, front bumper full plate, etc etc different? I've got everything I need for my 54 Chevy and getting close to bodywork and paint. I have an opportunity to buy a 54 GMC project that I could use parts towards a trailer and am curious about the front sheet metal. Kinda funny, I like the 47-53 bed, 54 Chevy cab (dash) 47-49 doors, and GMC front end.
