85-86 door body moldings on 87-93

The one issue I see is the window beltline trim. The 86 and earlier clip on the door edge, while the 87-93 use plastic discs riveted to holes in the doors so the trim can slide in place. Just something to think about if you want to keep the 86 beltline trim.

Just for reference, my '84 has '91 doors on it. The beltline trim holes were welded up. That's all that was necessary. The '91 doors even still had the correct holes for the older inner door handles and unlatching rods for opening the door (uses 2 metal clips instead of the single plastic one). And by using newer doors, you can put door speakers in easier because they had the holes in them. The body lines match up perfectly to the fenders and quarters too.
