Yes, that's the counter shaft cluster gear. For a Fbody LS1 it's tremec part# 1386-077-008 but you may only be able to get it as a complete matched kit that includes the 5/6/R extension shaft (1386-410-008) Check with your favorite Tremec dealer or one of the board sponsors.

I have 3 of the cluster shafts in my spare parts pile, not sure if they'd make it to you by Thursday.. Send me a PM if you're interested.

I have the piece "B" in your picture. It's recommended to keep the extension shaft (Pictured below. It's splined onto the end of the cluster shaft and has the 5/6 synchro) as a matched set with the countershaft, which is why I don't think just the cluster is sold separately.

They are offered new from Tremec for about $600 , typically a good used one is about half of that price .

To be honest with you , I am not sure if it comes with an extension or not for that price . I have never bought one new . I have several used ones on the shelf and several more cores if needed .
