I wondered if anyone has developed a list of parts on our cars that are interchangeable with parts from other cars. I noticed that the interior light on my car is identical to the interior light on certain Land Rovers and I plan to order a new lense from the Land Rover dealer to replace my broken lense. I only assume that AC used off the shelf parts sourced from other manufacturers in the MK IV. It wouldn't have made much sense for AC to develop its own items such as lights, switches, dashboard controls, wiper and heater motors, etc. when those from other manufacturers were already engineered and available. If such a list doesn't exist, maybe we can, with collective knowledge, get one started. John AK1103
