Does anyone know what size bolts attach the front quarter panel, at the bottom, behind the front wheels to the body?
The drainage was blocked by handfulls of dirt and the bolts rusted and they are wrecked from me trying to get them off.

I think they are 1/4" diameter and 12mm long. I'd like a few opinions cheers

 

10mm heads, same thread/pitch as every other 10mm head bolt on the car.
