73 door work on a 78?

[K20Chevrolet]

hey guys so i had this posted somwhere else but ill see if i get better help here. so im in the middle of rebuilding my truck and I was in the shop last night with a couple of the guys and he pointed out that one of my doors were from the wrong year (truck was in a accident and doors were rusted beyond repair had to order new ones). I did a little digging in to my order forum and compared the 2 doors side by side. sure enough one door is from the 73-76 style. Now my question is will this door fit and work the same as the OEM 78 door would? like still able to use the old windows and vent window and everything else? Or is there modifying work involved? if that's the case i guess ill see if LMC will take the door back and exchange for the right door.

Any thing will be appreciated
