Here I've added the front hoop crossbar to the Chris Alston rollcage. It's dropped down to allow access for welding.
In this view the main hoop is dropped down to again aid in welding the cage.
This view is looking in the back window at the cage in the dropped down position.
This is the junction of tubes behind the driver's head. I added gussets for extra strength.
This is the same corner from farther back showing the main hoop atop the 2x2" frame. The bar running to the rear passes through the rear deck tray. The diagonal brace for this side is welded in place and I am fitting the cross piece for the other side.
I am using preforated angle iron and spring clamps to position the cross brace as I cut, grind, and fit it to match the other continuous bar.
This is looking from the bottom rear of the car at the same area.
This shows where the tube attaches to the frame and also shows the rear deck tray support attaching to the rollcage rear tube.
This view is through the driver's door.
This is the attachment I used on the front of the cage. The 1x2" frame I added to the underside of the car running along the rocker panel seam is exposed here to allow the 1.5x1.5" tube (with bolts) to be welded to it. The cage is then welded to this tube and to the unibody creating a solid, secure attachment. The siderail tube will weld to this point as well and run up to the main hoop.
