Carter BBS rebuild.

I see you haven't bought one at a parts store lately.

Wrong. Six weeks ago I was in sudden need of a BBS kit. The regular normal Parts Plus store down the street from me (in Seattle) had it the day after I called it in.

I checked with rockauto, and local NAPA Checker and Autozone stores. They couldn't even order it.

Yeah, they could. They just didn't feel like helping you for whatever reason. NAPA kit number 2-5500, Walker number 15483A (many other brands also use this number), Standard-Hygrade kit number 1636. RockAuto shows the Standard-Hygrade #1636 in stock for $13.47. Similar pricing from NAPA for the 2-5500.
