This is the 742 AL case



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.



oups I think you lost me (pining) what the hell it is???:-?
how can I do that???
have both case and already bought the crush sleeve eliminator
maybe 3 years ado
wife will be happy it is in the entry closet from this time:D

how much cost the AL 742 case???
please tell me you have one used and you are willing to sell it!!!
