Thanks for letting me join. This is my first build and I picked a truck that may have less then 500 ever built. Good news is it is still just an 61 4x4 Apace so parts are still out there or can be found new. These trucks were built by 5 diffe companies from '61-'66 for airports, loggers, military and railroads. I bought a 1978 GMC Serria Grande for the axles, trans and bellhousing. Housing has a Crack and tranny is not coming off with out pulling motor. I have the original 235, sm420, corporate axles. They could be for sale if anyone is looking. The motor has 120 psi, hei distributor. The carb was missing parts and rebuild kit did not fix it. I bought a '86 sbc that was in a dodge hot rod that got totaled. Motor has 2500 miles since it was gone through. I need a good highway trans, looking at NV4500? Thinking of keeping the divorced trans case? If easier to use transfer case one of a 78 gmc that has the parts to marry it. I have new leaf springs, converted the rear to disk breaks, new gas tank, new break line ready to put in and the front u mount for the 350. I need to put in power steering, new gas line, break booster, clutch master. If you guys know what I am looking to replace, please let me know what you would do. Again, I have never done anything like this. Thanks for the help, and if you know anything about these trucks please inform me.
