Thanks StickGT1. There was no other option locally, so I bought the expensive M12 1.5 helicoil which was $107 vs. the 1.25 that was $65. I debated between changing the bolt to a 1.25 pitch and get the cheaper helicoil but I decided to stay with the original bolt. I used a coil and three threads from another coil and got it fully repaired. It worked perfect. I torqued it at 105 NM as per TIS.
