Car is in storage and im going to take it out, but i forgot to go buy some new bolts and i don't have the car near me as its at a storage place. The stock ones are pretty stripped to the point i have to use a 8mm tiny wrench because a socket wouldn't grab it anymore.

Anyone know the size?

the heads of them are 8mm, but the bolt itself is way bigger.

You can just buy replacements for them. Check the 'help!' section of your parts store...
