Edit: After a quick search I see others have dealt with this issue.
I used a cheapo autozone tap and made threads, probably not the best thing but really didn't have other options as the chaser didn't work.
I will run it as is if it torques to spec and keep an eye on it, worst case timesert it if/when the compromised threads fail.
_______________________________________________
I have some gakked up female threads on a few of my FCAB mounting points, I was able to use a thread chaser to good effect on 2 of the 4 holes.
Unfortunately on the other remaining holes the chaser will not thread all the way in and I don't want to force it and break it off.
In the holes that still have issues I put in a brand new bolt, ran it in about 3/4 up before resistance is felt, removed the bolt to find distorted threads on top few threads of the bolt.
I really have concerns using a regular tap as I do not want to remove material in this critical area.
Any tips/tricks would be appreciated.
