This is the 742 AL case now beyond 500 passes, mid 9's full weight b body leave off t-brake at 5800
The stl case has a cap deflection issue from what i see when they fail, even using the MW billet cap and seen the same situation.
What i am going to try are slightly larger diameter studs and pining it so the cap can't move, then i believe the 742 stl case should be as good as the AL case.
