I have a design for a bumper and am looking to fabricate a few up to try and sell (if they do sell one of the purchases with the proceeds will get my cheap ass orange). I will be using my '79 K5 as a model. I'm planning on using the factory holes on the frame and 4 grade 8 bolts to hold the bumper on. My question is what years would have the same frame holes as my '79? And what about pickups and burbs? I will be making both front and back so if you know both that would be great. /forums/images/graemlins/thumb.gif
