I did the Chassis on mine about 2 years ago. I couldnt afford a new one, so got a gooden from a Breakers in Great Yarmouth for £250. It came from a 1996 station wagon.
When i was looking, i only found a couple of people doing the 110 chassis. I think the best are Marshlands as they supply Land Rover if you buy a chassis from them. (I know because the guy behind the counter who gave me the £2500+vat news) told me. :D
