I have a 79 K10 with quite a few modifications. Enough in fact that I have started to seriously consider a roll cage. It was pointed out to me that JEGS sells a 12 point cage made from .134" wall mild steel tubing with 1.625" O.D. The application is 73-87 C10s. Has anyone had any experience with this product? I'm thinking hard about buying it and I'm curious how well it will fit. Probably I'll just keep the 8 point part that goes in the cab. Prebent and prenotched tubing sounds great and I'm sure I can make small mods to accomodate minor discrepancies. Thanks for your input.
