Anything is possible!
Just make sure that however it is fixed it has some strength in it!. You don't see that part of the car, so it doesnt really matter that much what the repair looks like.
There is a box section that runs along behind the back wheel that the top of the shocker bolts through. This is on the outside of the car, seperated from the inside by a single thickness of metal.
If i were fixing holes round there I would concentrate on replacing the sectional bit with something stronger, and then fix the hole in the metal sheet afterwards.
If that bit of your car is that bad then it is likely to need some attention elsewhere in the near future!, so you should have a good look round elsewhere now.
The bracket just behind the shock where one of the suspension arms that holds the rear axle fixes too is also prone to rotting.
I've not been up to delemere ever, but i sometimes work not far off, in winsford!. Eventually I will find some 99 owners who are actually close to me
