What are the markings the the BC spec IV's? I searched for hours and found one post that said "A" and I even called BC and they said it should have a IV or 4 on it. They said the spec 3's have a "T" or "TA" on them.

 

Nevermind, I found this in one of the threads. It will have an "A" and "4" Stamped on the end or possibly a "B" if they are a previous gen.

Thanks
