trying to save my old opti for a back up, i pulled it apart to see if there was any oil in it, and now i'm in need of a place to get the o-rings or gaskets that seal it together because mine were leaking a bit.

 

I don't remember the part number, but check out Shoe Box's website as he should have it listed there. I just did the replacement recently when I pulled my opti and you can get them from your local GM dealership as they have em' in stock and pretty cheap.
