Modded Factory K-5 Rear \"roll\" bar to fit pickup I had a 79 k-5 (Rust In Peace). Before junking it I took out the rear factory "roll" bar thinking I might have some use for my K-10 pickup. I decided to use it as a light bar in my k-10 this year for plowing and such. I flipped it around, extended the legs and also extended the angled legs that mount to the fender wells. Here is a pic. I have to wire the light and stuff now. I used .120 wall for the extensions. T.J.
