55.2-59 Radiator support swap.

those little angle brackets on each side, that retain the crossbar with the hood latch attached, would be easy to fab. I have pics of the dimensions etc if needed. the bar behind the upper grill surround is a separate piece from the other cross bar with the latch.

what did you say your frame is from?

Sorry been into a hundred other things.
The frame I am using is a 1980 C20 2wd with heavy-duty brakes.

What I have found out so far. The 55, 56, and 57 GMC fenders are the same as the 57 chevy fenders. The lower valance panel from 55 chevy is not going to work. The GMC valance is a smooth panel that is actually part of the grill opening, where the chevy valance is hidden by the grill.. The Chevy hood latch panel appears to fit perfectly with the GMC hood and hood latch. So it appears that I need the filler panel that holds the center mustache to make the GMC parts fit the chevy hood latch panel. The rest of the stuff I need is mostly universal between chevy and GMC.

So my next goal is to get fenders, inner fenders, and the few GMC pieces that I need.

With it cobbled onto that later model frame you are going to have to do a lot of cutting and fitting before all is said and done.

I don't know what radiator setup that 57 GMC that I had out here for years had as the truck had a 283 in it with a power glide. It was a total rust bucket though.

Looking at the radiators there are probably some very noticeable differences in the top panel over the core supports. That and you may be seriously modifying that cross piece under the radiator for clearance.

All that part is done. Rad support is installed, radiator is mounted to support. Hood is on it and everything looks good. All I need to do is figure out which pieces I need to mount the GMC center mustache to the chevy hood latch panel. And since the Canadian GMC came that way from the factory I just need to know what pieces they used.
Only cutting I will have to do will be modifying the drivers side inner fender to clear the steering shaft.

Test fit so far
