WOW, that truck is FANTASTIC!! ...but where's the air-horns?
I just figured that there would be at least two sets of horns?

Anywho, I'm swapping axles to a Dana80 and solid front from a
'00 3500hd and don't think I'll be going back to the hydra-boost that came STOCK on my '64.
It looks like someone 'went through it' at some point in the not so distant past.
I wonder if it would fit yours?
PM me and we can talk.
