I have searched and called part stores for this part, the closest I got to was ACDELCO part number PVS-120 which they don't have. O'Reileys auto has to check with corporate to see if they can get it special order from another company....what is with these people? Why isn't there a part of this engine when you can find parts for others? Is there a replacement some of you guys have used? The part below, I saw it EBAY, looks exactly like my piece...what is the difference????

I know it's MOPAR, but seriously, it could be a twin to the piece I have on now, except mine was black. It crumbled and I didn't see anything internal showing a limit on anything pertaining to engine requirements...
