This an SCCA IT cage, though it is based off the best rally cage I could find for stock type suspension. The diagonal is not installed yet in the pics, it will be added after fitting seat and painting most of the interior, as it makes access to the center of the car difficult. All tubing is 1.625x.120 DOM - a little heavier than necessary. Same with the mounting plates- 3/16", .080 is required. Door bars are bottom along rocker/top slants forward under armpit then angles forward past the hip, with vertical ties between. Tubular gussets at windshield. Snaked the dash bar in like it was supposed to be there. Will be totally hidden by the dash. When the door is closed, you can't tell the car even has a cage except for the rear brace in the side window. More pics tomorrow nite- car is back in my shop tomorrow.
