The bar across the top of the cab is from a factory 75 Blazer that we cut down and modified to fit as it is shown and the rear is from a mid 70's Blazer with no modifications, both 2". The rear portion connecting those two bars is also 2" and the front cage portion is 1½" It is only bolted to the floor for now, not sure if it needs to go to the frame or not at this time as my floor and body is solid. I need to put another coat of paint on it and some padding and it's good to go. Pics are under roll cage album.
