Actually, I have to send a couple of £ to a guy tomorrow via Paypal for the internal door handle - Will ask him if he has one - I assumed most would want to sell the box complete..
I see what you mean - but if you take the bit off a car yourself at the breakers that'd be OK The switch is really only an ancillary part to the box so I think you'd be OK. My local breakers yard is very good like that, they let you have cylinder heads off engines for example where most other breakers will make you take the whole engine
