I am in the process of replacing the front transmission mount on my Eg6. The three bolts that attach the mount to the transmission appear to be damaged from when I removed the bolts. When I try and torque them down they bite for a bit but don't allow to be torqued to 60 foot lb that are required. I am looking for the best option to try and fix this. I am not sure if a helicoil will hold 60 fT LB or if I can use some lock tight or thread repair or if I have to resort to drilling the hole bigger and re-tapping it.
