Why would someone cut the inside of a torque tube at the axle end with a torch? Or are they made this way... Yes cut all the way around that way
My guess is it's a late '32 or '33-'34 torque tube bolted to a '35 & later rear axle. Early tube needs to have material removed to fit over larger bearing on the later rear axle. A common procedure. Usually this clearance is gained by grinding. Your tube had the cave man approach.
Thnx, That answers a LOT... The truck is a 34 and had juice brakes on it, But I know those could be changed. Now time to try and decipher what year the rear end is for bearings and such.. And believe me there has been a bunch of caveman stuff that had to be fixed..
