I think that Mike meant to post that the 1948-54 (55st?) 3-speed trucks had column shift-mechanisms/assemblies?
19481955-stTim, per my parts books the 591615 case was only used thru '54 and then the 3845122 case was used '55-up...is this not correct?
I did have a brain fart in saying floor shift, it is in fact column as we all know...sorry for the confusion there.
