I am coming up with these two part numbers for an OEM Alternator replacement. Has anyone purchased either one and can confirm proper fit. If you have a different number let me know. 4U2Z-10V346-EKRM or YR3Z-10V346-ACRM Thanks

According to Rockauto.com ....... 2R3Z10V346BARM, 2R3Z10V346BDRM, GLV8616RM, GLV8672RM, GLV8943RM More Information for MOTORCRAFT GLV9051RM It is also the same as the V6 mustang with an 8 rib pulley. That is the only difference.

Thanks for the info. I did look on RockAuto as well but the 2 numbers I found were from Ford websites Looking for a Motorcraft number that someone has actually used.

Hey White Snake. Has that Motorcraft alternator been in your cobra for a while? The last Motorcraft alternator I bought lasted 9 years so I figured it was the way to go. Let me know that part number you used so I can get it on order. Thanks
