Ok thanks, the hole was tapped to fit a heli coil I put one in last night but the bolt for tensioner does not seem to get real tight so I’m worried to death it going to come out. I did not know I could drill a hole bigger in tensioner that might be a great idea heli coil is a 10.5 but od is bigger of course the threaded insert sound better I will try to order some just was wondering if they will last or just do the dang cover thanks for your guys professional help I really appreciate it
