Buick Regal GS 2016 - Some RPO (GNB, GNC, NJ2)
Hello I ordered those parts for my rear suspension:

Rear Upper Control Arm x2 - GM Part# 20900531 (it takes 2 bolts for this part and they are different as far as I know but I'm not sure)
Rear Stabilizer Shaft x2 - GM Part# 13281792 (it comes with one bolt, but the other one that goes to the wheel assembly I don't have the specific one)
Link Assembly x2 - GM Part# 13219171 (it takes 2 bolts too and they are different as far as I know but I'm not sure)

So as those bolts are TTY I want to know If I can reuse them or I need to buy new ones and if that's the case which one are those because I'm having a hard time looking for them.

Thank you, much appreciated if someone can help me

mark bolts with paint pen before removal then install them to same mark after part re installed. you don't need new bolts unless severely damaged or rusted

Thanks a lot for the reply I don’t know why I posted 2 things about the same.

I will use this for the reference, do I need to count how many times the bolt turns or just with the mark?

no just tighten the bolts to torque spec and then line up paint mark

Perfect, thank you very much for real.

I’m from Mexico but those parts here are impossible to find so I was expecting to have all the parts that I need to do just 1 trip to US and not 2 trips just for a stupid bolt.

Thanks a lot again man much appreciated.
