Well, if you reprofile them like that drawing, then i'm never ******* buying one! JOKE
Funnily enough, my bottom bolt always unscrews with the stud attached....
The long magneto bolt on my 62 SR was broken off at the head and it was a bugger to get the mag off. I ended up having to remove the timing cover and inner cas and had to drill the stud out. Luckily I did not damage the original threads . Plan on replacing the stud in the case and make sure it cannot unscrew out by coating the threads with JB weld or similar. will check both of the 2 long bolts that I do have to make sure there is no mag fouling. Thanks for the tip .[/quote]blue loctite will do the trick not JB weld
