midnight rambler 36 #2 Posted January 10, 2013 if you go to your parts store they should have the proper drill bit,tap and insert. also the insert tool, best to follow the correct bit size, the heli coils dont usually come out but i have seen them jump a thread as they are inserted due to the wrong person putting them in, dont forget to break off the little tab after you get the coil in place, Share this post Link to post Share on other sites
fourwheels0 191 #3 Posted January 12, 2013 well i didn't have to heli coil it. i just chased the threads and used longer bolts with blue loctite. they had short bolts in it. i think the one was loose and the torque from the starter just popped it out. only lost like 3 threads.
