my new AC condenser didn't come w/ the lower stud where the suction tube connects. I have to reuse my orginal stud.
1. are these inverted torx sockets metric or regular?
2.did I already booger up the torx star head? yes I had vice gripes but didn't use much force.
3.can I tighten 2 nuts together and grip on the 2 nuts to remove stud?

the co. that sold me the kit doesn't supply hardware

4.do most GM cars of 99 era share the same stud?

thanks for advice

 

1. There is no metric or regular Torx. Just Torx, Torx Plus, Security, Inverted. These should just be your standard E Torx.
2. Can't tell from the picture.
3. Yes, you can. It is likely seized in the aluminum though, and may require heat.
4. I do not know, but you could likely use any equivalent stud of any type.

Hopefully you got this figured out well before my response lol
