What engine would be in a GMC Truck the level above the Medium duty trucks. The closest thing I have found to match this thing is a picture of a 1936 T-26-B. The truck has free standing headlight pods. The cab is not the same as the 1/2,3/4,1,& 1 1/2 ton trucks. How hard are parts to find for these trucks? The truck is a 1942.
