Hello Everyone I am new to the post and new to restoring so looking forward to all the help. I have a 1955 GMC series 1 deluxe 5 window that is pretty much all original except it was converted to 12 volt before I purchased it in 1982. It is my first truck and I drove it couple of years in high school and parked it 1985 when I went into the service. Life took over and it stayed in the field until last month when I picked it up and trailered it down to Texas. I know shame on me, but hey it is spilled milk so I will have to just deal with it. It was running, but had a miss so will want to rebuild the motor, it is a numbers matching 248 connected to a hydramatic 100 trany and a torque tube rear end. The u joints made a lot of noise when I would let off the gas so I know that they need attention. I have lots of questions on the best way to get started etc, but I would like to know if it is worth rebuilding the torque tube and rear end. I would like to change the ring and pinion for drivability which I have seen in the post but haven't found any information on rebuilding the torque tube. The hydramatic was working fine when I was driving it but that was 34 years ago. I have no problem rebuilding the motor, but should I attempt the trany? Is it worth saving any of it or should I change out the trany and rear end for an open drive line? I know that I have written a book here sorry if that is not cool but wanted to get this started. I like doing a lot of research before I start a project so that I have a plan to follow. Thanks in advance for your help.
