1974 was a unique one-year only design for the LC in the 1970s. https://raleigh.craigslist.org/cto/d/1974-lincoln-continental/6654121482.html
Yeppers, these 74's were like an amalgamation of the 70-73 and 75-79 bodystyles. It's really noticeable in the coupes.
Nice car, but that rear bumper thing has to be fixed. Looks ugly as hell, and it's just begging to be caught on something else and pulled the rest of the way off.
If the cracks are not too bad, they can be repaired. I agree about the bumper, and you'd think the seller would've done that to make the car more attractive for selling.
