I have a question. I know that there is a difference when buying parts as early 1974 1/2 or late 1974 1/2. I was looking at my title and that states 1974 but when I check out the body drivers door plate it has Manufactured March 1975? The ID number on the title, body plate and the tag on the winshield are all the same manufacturer's ID number. Seems strange that the car is maufactured in 1975 but is tagged as a 1974. Is there some other validation I can look at to validate? Is there any physical /mechanical difference between a 1974 and a 1975 as a quick check? Thanks
