My daughters car engine seized-up so I got another engine from the junk yard. There is one little thing on the original supercharger that is different from the "new" supercharger. Below are the pictures.

I was planning on taking as many of the external parts off the original engine as possible including the supercharger. Mostly because I feel better about those parts than the ones coming on the "new" motor.

this is my original engine supercharger.
