It's a guy named Murray B Park in Ohio who is well respected in the Chrysler world and has a large selection of parts and parts cars.
If you click on his online shop - Chrysler - 1977 there are various categories like interior - mirrors - steering wheels and parts etc. He's a good place to start.
Am moving to Christchurch next Sunday and hope to import my 1973 Imperial LeBaron from the US (Wisconsin) in November funds permitting.
