The roll bar is secure however it does deflect 1/8 inch when grabbing the B Pillar and the hoop.
It needs the diagonal to fix this problem.
First we get the length very close to final and start to fit the tubes together.
Here is a closer view of the tube attachment.
The hand grinder shapes the diagonal tube to fit around the hoop tube.
You can see my writing in pencil on the bottom side of the tube to orient itself properly while fitting.
I cut the other end that faces down at the correct angle to match the main hoop.
Now just tacked in at the bottom end.
Had to take the diagonal in and out of the car many times to make it fit with no pressure. Ended up with 1mm clearance.
With the diagonal installed there is no more deflection.
It is tight as a rock.
