Hi Lee

The screws that attach the wing to the body can all be reused without any problem, the one that is low down under the side strip and connects into the sill will be rusted and probably shear off and need drilled out.

The most awkward nuts though are where the front edge of the wing connects to the bumper cover this is clamped on with a horse shoe shaped bracket with 3 studs on it.

Again it will most likely be rusted up and be difficult to undo.

May need to replace this bracket.

The valances are pretty much the same chances are the bolts will shear off and need replacing.

Can't really say what the painting costs would be but I'd guess at roughly

£100
