Seems that when I got my BG that it already had the sleeve installed and I didn't find out until earlier this week when I pulled my trans to replace the clutch. Great thing about PDM Snout Sleeves is that they have a LIFETIME WARRANTY!!! If you need to replace your TO bearing and have the sleeve already installed you will need a bearing number 614147 for the BD/BG non-turbo and can get the bearing from PDM. They have great service and I highly recommend them. www.pdmusa1.com
