I don't think that's right about the guts interchanging. Accoring to everything I've ever seen about the GMCs from that era, they used Spicer/Dana axles, rather than the Eaton manufactured axles used in Chevrolet.

Just saw this! Thanks. Yeah, that is what I would want to do anyway would be a complete housing swap.
