I am going to install a roll cage on my 76 K5. I plan to cut the middle of the roof out and install a minature rag top. I will basically measure about 2-4 inches in all the way around the roogf and start cutting. I think I will need the cage for structural support. Does anyone sell these? or does everyone make them from scratch. ANythng special I need to know? does anyone have a rollcage for Dummies hand book? I have air, grinder, metal sheers, cutoff wheel and a grinder. I do not hve bender but I could get a friend to do that part. I also have a wire feed welder.
