This entire piece:



Obviously this one has a rag joint eliminator already. I need to know the part # for a stock one.

The above tells you every part number you will ever need. I'd suggest DL'ing it and keeping it for future reference.

P.S. If you are looking for a new replacement, this part doesn't seem to be available from GMPD.com anymore so not sure it will be available anywhere else new.
