My 67rs 327/275hp built in Dec. of 1966 is supposed to have a 1111249. Mine has a 1111150 that was supposed to be in a 283/195hp (manufacture date Dec5/1966). Is it possible the wrong numbered distributer was put in the car because maybe they didn't have enough correct distributers that day? Date code for this "wrong" distributer is right on for the build. This 1111150 seems to have a worn bushing, but I don't want to rebuild it unless it came with my car. Thx!
