Looks like some confusion in this thread to me.

The stock bar uses a bolt that threads into an aluminum hole (I think). Easy to strip. Persion said he stripped turning a bolt and might need to re-tap a hole.

The aftermarket bar in the photo is attached to studs that take a nut. I didn't get the impression there was a problem with the strut studs/bolt.

Ok, could be. I'd do the same thing in reverse. Take a tap and re-thread the same exact size. Put the intended bolts back in and torque down to 30.5 Nm (22 ft-lb). If it takes, just re-torque in a week and then a month to make sure it holds. Those bolts are also one time use M8x23 Torx bolts.

Now, if that doesn't work, I'd probably go with a Helicoil that is made for aluminum. You should use a Al compatible Helicoil.

I like the Helicoil recommendations. I have this same problem where I nearly stripped mine but stopped just before it completely blew through the threads - metal bolt - aluminum hole

I figure I get one more chance to remove it and it will never tighten properly again. I think I will get one of these coils and sit it on the shelf.

Heilicoils work good,,, but to me,, its a temporary fix... U can also install threaded inserts,, I think its a much more permanent solution than a helicoil...... Its a one time fix,,, will last forever...

Helicoil is a permanent fix. It is totally acceptable for a permanent solution and it as good or better than the original threads.

I agree a helicoil is acceptible,,,, and works good,,,,, But a threaded insert is stronger and holds a higer torque value.... After having to repair a stripped helicoil on numerous different situations ive always used a threaded insert to fxed a stripped helicoil .... Like for example when someone strips a helicoil on a sparkplug .. or a cylinder head bolt, or a intake manifold bolt ,,,, The helicoil is done,,,,, in goes the threaded insert for the solution,,,,,,,thats been my experience dealing with helicoils,,, and opinion on why a insert is a good way to go...

Any recommendations on where I can get a threaded insert and what size I should use?

Orielys,, Napa. even hardware stores carry them.. take ur bolt with u and fit it to the right size insert . the good thing that i ;ike about a insert is that for any reason it gets stripped,,,,, its easy to install a new one without having to re drill or rertap,, U just get a easyout and extract it .. and srew in a new one and,,,,, back in the race..

I think someone mentioned to just retap and go up one bolt size... Thats a good solution too.. If u dont mind having a bigger bolt on one side..
