Hydromatic-equipped '56?

[Brad54]

I was at an old junkyard today, and found a '56 GMC with the engine, hydromatic, steering column and even the "Hydramatic" emblems on the front fenders.

The rest of the truck is really worthless--totally rotted, even up into the roof. But all that auto-trans stuff is still there.

This is actually the second hydramatic-equipped '55-'57 I've found in a junkyard this year--the first got crushed before I could learn anything about them.

How rare are they, and is it worth getting, or is there no demand or interest in them?

On the plus side, I did score the radio speaker box above the windshield! I always thought those were kinda cool... it needs a little work, but I've always wanted one so it'll be worth it. I'll probably put it in my '61 Suburban.
