Quality Bodyshop/Restorer/Classic Specialist (Northwest / North england)

I'm in need of a quality/Highly recommended place to have some work done on my MK2 XR2 . It needs some work done to fix some pretty bad corrosion around the rear beam trailing arm mount points (common problem) . Not looking for a quick fix, i'm after a proper job as the rest of the car is in pretty outstanding condition. As you can see !

Anyone know any ford specialists, or can recommend a quality establishment ? Needs to be in the northwest ideally as the car has been stored for two years and has no TAX or MOT .

Thanks, Nick
