Thanks for the replies!
Gordon:
I noticed while working on the 1.5 ton Chev that someone "clocked" the tire mold wrong when they made the tire as the tread is not staggered like NDT's should be. The tread lugs are directly across from each other.
Andrew:
Thanks a lot for the photos. They really help and are very much appreciated!
Bob:
Here are a few photos of the tank cast piece after I cleaned it up a bit.
Noticed that it appears to be made of copper? Was tarnished to a deep blue-green on the inside before clean-up and the brass pieces,(arrow), are much yellower than the reddish tinted casting.
There is an "R" stamped into this casting also. Does this mean it's for a right side tank?
There is a notch cut in the front fuel tank support rail even with the fuel outlet in the tank. Is this where the fuel line should be routed?
If this is a left-side tank my brass tank outlet is facing the rear of the truck, and the casting can't be rotated 180 degrees due to the "reserve" feature made into the tank.

Thanks, David
