Need speedo sleeve for 89 700R4 - Third Generation F-Body Message Boards

It is a 9 bolt so I have 3.90 gears now but it came with 2.77 stock. The stock piece is a black plastic cover. The speedo is cable driven. I assume probuilt put in a 15/45 combo for the 3.90's. The stock gear had a metal shaft and the new one is plastic. This is the part number I found : 25512339 is this correct for the new sleeve????

That's the right one for a 700-R4 / th350-c / th250-c with a 40-45 (might be 41-45 teeth driven gear.

I thought it was discontinued; when I went looking for one through GM it was. If you need one, I have a couple new ones.
