i personal wouldnt use eighter but i do like J B WELD best if you ask this qu w/ was the last thing you but threads into ? fill that hole w/ anything its gonna be a disaster !!!! trust me cant you clean up the hole a bit and you have the screw that messed it up , if not doesnt matter get a drill guide and a set of taps they make kits for this as well as ask someone at the parts shop that will help you drill out the stripped out threads and BE -careful of how deep you drill CK THE DEPTH OF YOUR HOLE if you drill and re tapp all is good and it leaks something THATS costly GOOD LUC but try too save the threads and hole first b-4 filling w/ jb weld - cant you mount the coil pac off some other bracket?
