Subject:Re: Header bolts broken

The front bolts are the problem. The studs in the rear were easy. I am
getting a helicoil kit tomorrow and am going to drill and fill the problem
bolts accordingly and replace them with stainless. Do you know of a place
nationally that I can get stainless M8 1.25 bolts for the replacement?
thanks, Cullen
