Need info on parts swaps-66GMC to 62 Chevy

[trapperjack]

Going to be pulling some things from a 66 GMC to use on my 62 Chevy, want to make sure what fits first. the GMC has a 305v6 with the bigger gas tank, but was always on propane from day 1, so I want the bigger tank. I need the whole e-brake set-up, looks the same. Outside heater box looks the same. I need a steering box and column, but the GMC is 1/2 ton 2wd, my 62 is 1/2 ton 4x4. And door handles, are they the same. They look the same from the outside.
Also, if anyone is needing some things, I can take pics this weekend, and check prices for you, he's pretty reasonable, just got the truck for the 305.

Thanks.
