I’ve been told they are supposed to be replaced but for stretch bolts if they are spec’d 90deg turn after torquing it’s ok to reuse but if it’s 180deg then replace it
I would only reuse the bolts in a situation where I had to put the car back together to get to work the next day and I wasn’t able to obtain new bolts that day.
On a different car, it only took 1 bolt to loosen for the mount to fail. It’s all fun and games until you back out of a parking spot and your shifter is in the passenger seat in a sketchy part of town.
