I need some help with finding parts for my 1980 280 Euro. Chassis 123030 engine 110923, gas with carb and transmission 020458 18. All of the parts sites I go to don't have my car. Are any of the US spec cars compatible with my car. Are there any places that specialize in Euro-spec W123's. I am not finding any helpful info with my searches.

Some guidance would be appreciated. Thanks.
