USCT Inner Fender Shock Tower Brace Kit - Fact or Fiction?

I've finished installing AMD inner fenders, and patched the floor brace from fender headers. I've read about the USCT Inner fender brace kit, and pulled the trigger on the credit card, But once I've received them, and tried a test fit, I got cold feet.

It appears to me, they put a lot of stress on the shock tower.... I'm looking for any A Body members who have installed these, and can tell us, if these are Fact or Fiction they do work??
