Flathead Illiterate

I'm doing a mechanical restoration on a 52 F1 with a bone stock original Flathead. This truck belongs to a big time goldchainer who needs a manual just to tie his shoes and insists on keeping it 'tiqued.
The problem I have is knowledge on parts interchange. The truck has a busted exhaust manifold. I have found plenty off outlets for car manifolds but come up empty on truck . Do they swap out???

Need as much info or links as possible

 

The only way to fix that is zoomies through the hood. Tell him it was a rare factory option.

 

give them what they need not what they want !!! a nice new set of fenton exaust manifolds , speedway sells um.

 

Pic? I have a pile and I gave up one RH exhaust for an 8RT in a F5, believe it had the front of the motor crossover, still have the left side and others. They should be easy to find used. I have never figured out how they get busted.
