Thanks guys, I'm having a really hard time finding a tap that is 6 inches long...I'm thinking the head has to come off for me to do this
more work than I wanted to do but it might be my only option without spending a bunch of money. I'd helicoil it but that would cost more than just a tap and bolt I think
I was looking at possibly going to a 5/16 inch tap and then getting a 5/16 bolt to fit in there...saw those at ACE
I believe a 5/16 is just up from a 6mm but if anyone knows for sure please let me know...
