JoeDiesel,
I stopped by my dealer about my bracket loaded with a print out of the TSB. They had not heard about it, and didn't seem to care. If it was broke and under warranty, it didn't seem to matter if there even was a TSB. They even used the print out from Genos to verify the p/n's.
At any rate, we went over to a new truck and popped the hood ... ... it had the cast and not cold formed bracket.
If your truck comes in and has the steel stamping, tell them to go ahead and order the cast bracket instead!
