I decided to make the side bars and cross brace to my roll cage removable, After looking at some weld in cage bungs ,I decided to make my own. I made them from 1 3/4 solid CRS round I have here at the shop. All my tubes are 1 3/4 .090 wall DOM, the cowl bar is 1 1/2 1/8 wall DOM Tube. Careful attention was paid so the tubes clear the door panels and seats. everything is tacked into place and I will Tig weld them into place when I get the car apart and ready for paint and on the rotiserie, this way I can weld all the way around the joint. The side bars are not to intrusive to get in and out of the car , the rear bar can be removed for rear passengers. I plan on making some plastic covers (probably out of some UHMW plastic) to slide over the cage bungs when the bars are removed.
