Super straight 1954 GM/Chevrolet 3100 pick-up frame. I purchased with the intent of putting my 55 First-Series cab on it but I am going a different route with the build. The frame has absolutely no cancer and no damage whatsoever. Has all 6 running board mounts straight and intact. I will answer any questions to the best of my availability. I purchased this for my 55 First-Series truck with the intent of using a 1954 bed. As far as I know, any 3100 frame pre-1954 will require some modifications if you wish to mount a 1954 bed. I can't seem to upload photos onto this listing so please email me with any questions or if you would like to see photographs of the frame. horribleharp@yahoo.com
