hey did u ever try taking the back seats to a shop !! im pretty sure they can custom fit them with a a few mods and cuts to fit them to ur back seat of ur mustang coupe !!

i noticed that the back rest are diffrent how about the the bottom seat part are those the same on the coupe or those didnt fit either !! ne ways if the entire back set didnt fit just take them toa shop they will be able to do it !! and it wont b expensive cut all it needs it a few mods here and there!!

Hey, I'm not sure if you've found a coupe leather set yet but I just saw a set being offered on a post on another site for $350, shipped.

A couple of things: I don't know how good the set is aside from the pics and I noticed that the headrests have their logo sewn onto them. If that's ok, you can always buy a new set of headrests that are just plain. Anyway, I'd like to post the link but I'm not sure if it would go against any rules here. Reply if you're interested.

Good luck.
