Difference in doors?

[dooce]

I've noticed that there are two different parts numbers for a new door depending if you have 73-76 or 77 and later. I've also noticed comments on people mentioning differences but never putting it in detail. Are the two doors interchangeable? I have taken a look at a set of 76 doors, and a set of my 86 doors and cannot find an obvious difference. Am I just not paying enough attention? I didn't think they would reproduce a different door for something so small, just like they don't produce a 79-80 specific hood (or not that i've seen). Please someone shine the light. Thanks DOOCE

The 73-76 doors have a shorter door panel and a lot of the door is exposed on the inside . The 77 up doors use a larger door panel and they have provisions to mount the door panel . If you have a 73-76 truck and you buy later doors , you will be able to see the mounting points for the newer door panel style . If your truck is later than 77 , you can use any door shell you want but you will have to drill mounting holes in the door . The window regulator shaft is also shorter on 73-76 doors than on the later doors . If you are buying new doors , get the correct one for the truck you have . If you are looking for used ,complete doors , you probably want to get the same year doors also since the vent windows are a little different depending on the year as well as the thickness of the glass itsself .

Is that all that is different? I remember somebody mentioning the top of the door or the door frame being slightly different? I don't need new doors, I was just curious. Thanks monroe

f.monroe nailed it, he is exactly right. Those are the only differences, the tops of the frames are the same.
