Hank, I checked the handles on my '51 11/2ton truck and they are loose enough that romoving the set screws would let them fall right off. Yours must really be corroded on, or someone glued them along the line.
If possible I would try heat or maybe drill into the handle to the post they are on and then either use a makeshift puller going through the drilled hole to the shaft or thead the hole and screw in a bolt against the shaft.
Just thoughts. Sam
