i'm rebuilding my lt1 and my water pump drive shaft bearing seems perfectly fine but i think i should change it anyway

i went to my local dealer and they gave me a part number of 10219554, and a price of around 80 bucks
i tried looking online and gmgoodwrench.com and i cant find this part number anywhere, the only one i find is 908101

how do i find the part i'm looking for online, how can i order it online and how much does it usually cost?

 

http://www.gmpartsdirect.com has it for ~$45

thanks alot

 

Do you have to replace the gear? ive got 70K on my engine and pulled it out and it looks fine? just wondering if you guys have run into problems with reusing the shaft and bearing.

 

Pace Pontiac 1 888-522-8163 new shaft and gear $37.00 you cannot afford to not replace it since you have the engine apart . 93ZTED
