looking for roll bar application question

I have used a couple Art Morrison kits and was very happy with each. One C.E. and no complaints there either. If I was shooting for a sub 9 second cert , I'd more than likely far it out. But I just put a Morrison 10 point kit in an early A ( mild steel ) and have every confidence that it will get through tech.
I did the mini tub and moved the leafs , tied the subs and am pretty sure it is right. But besides welds , geometry and locations are far more critical in a faster car.
