I'm not sure what you mean by odd driveline... Are the 158-1/2" trucks that rare? I'm just after the front section of the torque tube... Yes, ideally I would swap to open drive, the problem is finding the parts either as a whole or or individually... It would make more sense just to swap axles and the rear transmission cover and be done with it, provided the location of the center bearing is the same as the closed driveline...
