I went and look at the helicoil kit. IMHO..I cant trust that to hold my Bolt in for the caliper. So I decided to go get another Knuckle.mrs.jeepgod said:Go and get a 8mm helicoil kit. I believe it has a 1.5 pitch. Take the good bolt with you to match it up. The kit comes with the tap that you need. The drill bit size is printed on the package. Just drill slow and straight! Piece of cake. If you are afraid to drill and tap it, any auto shop or machine shop will be more than happy to help.. Good Luck!
