What you are showing are seat rail bolts, and although they look like they've been partially beaten up, they are still in good enough condition to be removed when using the correct driver.

The only problem is the clown attempting to remove them using the incorrect tool. Get someone with an actual value and mechanical bone in their body to remove them.

Yes, going by memory, it should be a 10mm, but it needs to engage properly in the bolt, so all crud and debris needs to be blown out of the head first.

You can buy replacement bolts at the dealer... Doubt you'd find them at a random parts store. You'll find them online I'm sure, if you prefer that.

They are the butchers that damaged the bolts so don't eat anything yourself.
