I've seen Jeep and S10 4WD T5's adapted to torque tubes.
There are no kits available for it, you would need some custom machine work done and would probably have to shorten the TT as
well.

Easiest thing to do is swap a '55 to '62 1/2 ton truck third member with 3.90:1 gear ratio into your existing axle housing and have a new driveshaft made. It's a bolt in deal.
