Hello. I'm from Poland and I have a big problem. Maybe You can help me with it. I have old cadillac fleetwood limo but I'm not sure what year is it. I think it's maybe 80-83 years 6.0L. I need carburetor to this car but I saw for many models are different carburetors. What I should do with my problem? Is it any standard carburetor will work with many fleetwoods? Thank You very much. Best regards
