Well, it looks like my truck season is over. I knew I had a questionable donut gasket on my cabover so I removed it and sure enough it was shot. I order and installed a new one and found out pretty quickly that I have a much bigger problem...
The intake manifold above the carburetor is badly cracked.
This old picture pre-restoration shows the location. It is on the front part of this "square area".

Pretty bummed out knowing that parts wont be easy to find and that I wont be able to cruise for a while.
I wonder what would have caused a crack like that.
