We're seeking an accomplice in the UK that can maybe help source used/take-off Vauxhall components with which we'd like to try a few things. Send me a PM and we can discuss what we're thinking.
He sells on EvilBay, too....name is close to his domain name.
I was resigned to having to order a Wipac headlamp bucket from a Brittish online dealer and pay hellacious shipping to the U.S., but this guy had just what I wanted and was quick with the parts. I was pleasantly surprised and will order from him again should the need arise. Not sure about Vauxall parts, but if you contact him via his website he'll respond fairly quickly, or at least he did for me.
