I have searched for an hour and i cant find any part numbers for this T.S.B. #02-07-31-003A. If you know them or if you know where i can find them please respond.

Here you go, there are 4 parts total. The best price I have found is from parts4chevys.com (tried gmpartsdirect.com but they do not ship to Canada). The pipe is $80 US and the other 3 parts are under $5 each.

Hope this helps.
