Hi,
Can you post some photos of the car, I'd love to see it.
If you look through my thread you'll find relevant rust repairs

I don't know of any repair panels for front wings, you'll need to make some I think. There was a post on here offering two new-old-stock Volvo 164 wings, but they have surface rust and were expensive at £250. Don't know if they are stilll available.
Good luck with the project. I'd really encourage you to take photos and document it on a thread on here. It's really worthwhile to do it, in terms of motivation, advice and ideas. And as a result of doing my project thread, I'm now in touch with several new friends around the world.
John
