Well to fully disclose my situation - I wanted to maintain originality on the outside and as much of the original chassis as i can. When my uncle was working on the truck, he did the brakes - but never added brake fluid. That was 20 years ago so - I need to replace/ rebuild at least the MC and wheel cylinders. I am also missing 2 drums. So with that plus the fact that I would love to make it more highway worthy with a friendly gear set and better brakes.........leads me to the mods. The truck has a manual trans - rebuilt and lubed. I intended to keep the manual trans, which I thought would require the use of the torque tube. I would love to change it to auto trans too but not sure how to maintain the shifter on the column. Changing everything over from trans back to rearend may be best way to go, but I dont want to lose 6 lug or the column shift.........
