This is from eper, top is the socket, bottom is the cupholder (approx Fiat prices) there is a Fiat parts man who frequents here, perhaps he can say if they are still available?
we have just got another couple of breakers, so I pretty sure there will be what you need in at least one of them. Best thing is the look on our ebay shop Ugly Bug Bits, or just check out ebay in general.
