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".

It is very tight in there but here's a picture showing the crack

No doubt it will need to be replaced. I am hoping all those folks out there that have taken there COE's and put them on modern chassis haven't just scrapped all the original stuff.
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.
