Hello I have a 1955 Chevy 3600 1st series 3/4 ton 4-speed floor shift truck. Do any of you know if the 1/2 ton and 3/4 ton steering gearbox and column are the same for this year? Also can I use a steering gearbox and column from a 1954 truck? I'm looking for an original gearbox with steering column and want to know if they're compatible. Thank you for your expertise!
