shop just called the guy says ordered me a VALEO with a 8 rib already to in stall $319.00 and $95.00 labor....i told him what i had done and he says you most likely will not find this kind of specially 8 rib on ebay and most re builders don't even have them not a big demand item ...he uses a re builder back east and my alternator will be here monday...... i called the ebay re builder who does not have a 8 rib in stock and hes sending me a RA number so i can send the 6 rib back witch by the way will line right up and fit a limited crossfire just not the SRT6 model 8 rib.....
