Not much to see there. Anyway, GMC did not go to leaf rear until 1963. I will say that I would not even go around the block from what I see. Find a donor and rebuild the rear suspension to original. Parts can be de-riveted and bolted to your frame. Trailing arm/Coil, etc. Maybe you have already fixed from 9 mo.'ago.
But I guess you only asked about an emblem. You got more than you paid for.
