Hello Tommy,
The corrosion around the seat belt mountings are not really the problem here its the number plate lamp that's the real problem.
You have to ask yourself do i scrap it or just off road it.
I had a similar dilema when my much loved disco failed on the rear windscreen wiper rubber.
Scrap it quick And as you seem like a nice decent chap I'll come and collect it from your drive. To save you the hassle of having to phone the scrapyard.
