So, After a couple days of PB-blasting, and propane torching, I managed to keep 1 out of 4 strut housing bolts intact, breaking off the other 3.

I have drilled out one of them, and re-tapping it is looking more and more likely. Does anyone know what the thread pitch is on those bolts? I know its an M12

Also, where can I pick up replacements? I figure the hardware store stuff is no good for this type of application.

Any tips or recommendations on how I should go about doing this?

Thanks!

 

Try threading one of your lug nuts onto it. If it goes, it's a 1.5, if not it's a 1.25. The hardware store is fine -- just make sure you meet or exceed the strength rating of the original part (that number on the head of the bolt).

 

Thanks, looks like its a M12 x 1.25

Does anyone happen to know the strength rating for it? I'm away from home right now, so I can't check the one bolt I have left.

 

I would use at LEAST an 8.8 grade, preferably 10.8.
