74 dodge dart same as 75?

Looking for some info. I want to buy a 1975 dodge dart for my son and I to restore. We want to build it like the one he drove in high school.that one was a 1974. Is there any big differences such as trim, tailights, bumpers, etc.? Would like to make this car close as possible. They look very similar to me. Thanks!

73-76 are very much the same, especially 74 and 75 and most people (99.9%) will not be able to see the differences.

73 still has taillights in the rear bumper
