73 and 74 were basically the same car. Motors/transmissions were the same internally, except the change from 340 to 360. I know the 9 1/4 replaced the 8 3/4 for or during the 74 model year. The other minor things that nobody really cares about have already been mentioned. Gas tank change, hood cowl vents, 3-point seatbelts for 74, all minor stuff not worth mentioning.

I get a good laugh when guys on here put down the 73-74 body style, seeing how realitively small of a change it is from 71-72.
