Hi Scott.
Thank you for posting the photo's of the sills on your car, also the excellent work carried out by Tom on the repair, your car is the first one I have seen with the actual jacking point rotted out, you can only imagine if anyone with the same amount of corrosion in that area if they had to changed the wheel over only to find the jacking point give way.
I think we all need to be very vigilant and pay attention to these sill jacking points on a monthly basis any signs of red rust lines get the sills checked out.
Tom will most certainly be a busy guy over the coming months & years on our car I am sure of that, most certainly the place to get the work carried that's for sure too.
cheers Arctic.
