I've read alot of old threads and signed up at NOS4GN to get the $100 acdelco but haven't heard back so I went to GNSpecialties and they have one for $84+$25 shipping. Both ship U.S.P.S which is good,anyway which one is the GNSpecialties chinese or U.S made? does it even matter at this point. ...What about that $39 dollar one at NOS4GN,any good?.I can get 2 or them,one for backup cause these things sound like they crap out all the time. Also I have a NAPA here in town but have a feeling the price is going to be crazy- I will phone them-at least its right here though. Which ones do NAPA sell,maybe I can cross reference the PN and get one off Ebay.
