Nice I think I'll go with the 35 dollar one / Whats the difference?

 

The one Shoebox very clearly lists on his website is an OEM GM part. The one that EFIConnection sells is an aftermarket part. Shoebox's prices are simply guidelines based on checking the online discount sources for GM parts. There is no guarantee you can buy it for that price, since it isn't reasonable to expect him to update the prices for 300+ parts every time GM decides to hike the prices.

 

You can get a replacement here, much cheaper than anywhere else
