YES THEY DO,( but it's for a Chevy)(GMC probly not far behind)in steel too, RB"s Obsolete just advertized such in one of their ads, but it wasn't cheap. You should be able to find a good used one tho, usually the easiest part to find in good shape for those trucks.
i have a chevy hood of that same era, it has a dent in it but it you cant find one i could sell it to you cheap!
Chevy is a different hood than the GMC, GMC's is rounded to clear front grill shell. But I'm sure you could trim a chevy hood to fit. HAHAHA lets be honest the panels on these things fit like shit to begin with anyway
I have a pretty nice one leaning against the wall in my shop. Surface rust only and a couple of small dents. PM me if you are interested. I am located in OKC. I have a complete 100 series and an extra front sheet metal set because parts are so hard to find.
German55GMC, Have you thought to post an intro? I just looked for it and couldn't find anything. I have friends in the Austin area and thought you might get a chance to meet some of them.
