I’ve just had a chat with a firm from the Midlands who can re manufacture the lower grille surrounds for us. Usual problem is they have to make new tooling first, cost £2/3000!
Presumably the tooling cost is 2-3grand. Shared over 100 sets of surrounds, plus labour, materials, mark-up and delivery, you're not going to get much change out of £100 a set I would think. I wouldn't be too hopeful of 100 sales though. Just a thought.
