I'm trying to find a new set of doors for my 75 blazer. Seeing as no one make them for the full vert I'm stuck looking for a half top set of doors. I found a set off an 87 with power windows and locks. Before I go out to look at them I just want to make sure that they will be compatible. Obviously I'll be needing to wire up the electronics and cut the door, but just not sure if there was any difference between 73-80 and 81-91 split.
