I've brought home some crazy projects, but my friend took the cake here.

Brockway started using the Mack 'style' cab in 1974 for their 700 series trucks (758, 759, 760, 761, 762,776's). Both the Mack and the Brockway cabs were manufacturer by Sheller Globe. Although they are similar in appearance, they are several changes that make them very different.

For the 400 series Brockway trucks (457,459, etc...) Brockway borrowed the F model Mack cab sometime around 1965/1966.

 

I just brought a Mack cab home. Only items I could salvage was cab and grille shell.
The fenders had a peak on them similar to a 36 Ford. The cab looks a little like a late 30's Ford. Almost rust free and complete. Grille is reminiscent of 34 Ford commercial p/u grille.
All the seats,frames,gauges any heater were good. Gl*** is good enough to make patterns.
Cab is about 2" wider than a comparable p/u of that era.
I'm leaning towards building a bobber truck with a completion look.
