im wondering if anyone can tell me a part # (delphi, bosch,gm, denso...) for the rear o2 sensor on the lsj, as ebay as many for about 20% of the cost of one from any autoparts store or gm. but ive bought things from these cheap parts auctions before and they didnt fit what they claimed, some auctions list part #'s for many makes, bosch, delphi etc. i wanted to cross reference the # to make sure it will fit. i had a guy from a parts place tell me they had a "special" one, differnent sensor from the 2.2 and 2.4 and nay other gm's for that matter. so jus wanted to check it in case im wasting my money.
thanks guys.
