I was wondering if you can shorten a torque tube driveline? I have a 1937 truck I am building into a street rod and found a 1939 Chevy truck cab off of an old grain truck. My idea was to take the old parts off of the 37 eng.,trans, and suspension and build a rat rod bobber. Also was wondering how fast the stock truck could go it was a 3/4 ton longbed.
