I was able to get together a complete set of cargo truck fuel lines! I'm going to take them up to NY with me and see about getting them copied, also.
Brake lines are also all figured out. The only issue is the vac hook up from the MC. There were a few different vac's used, and they were plumed differently... so that part will have to be figured out. One of my trucks had an early, the other a late, the third a civvy... all were hand bent lines
