I spoke too soon. Dealer called and parts told them I wont have an alternator(jeep brand) for a few weeks. No, they will not fit an aftermarket part temporarily as FCA wont cover for it. (even though FCA told me otherwise).
Anyway, I have demanded a loan car which I am now going to pickup, and demanded a large car of the same type as "I am going camping with family, this long weekend"
Kinda getting sick of this entire process, running around etc. I had wished I had ordered an alternator directly out of US and just expense it back with FCA. I probably wouldn't have blown a PCM either.
BTW I will claim back this taxi fare too.
