Aftermarket door shells

[A1971Blazer]

I bought a pair from LMC for my '67 build and had them painted an installed before I found some really good OEM doors.
Honestly, they fit but not as well as I had hoped. The biggest issue I ran into was the upper window frame, it's not exactly in the correct location in relation to the door frame in the cab and the windows did not fit properly.
When I put the vent windows and the glass in, the window contacted the inside of the door frame at the back and would not go all the way up. I ended up belt sanding (with great difficulty) almost 1/8" of the glass to make it fit.
I believe they were Key Parts doors. I bought them because I had gotten my stepside fenders from LMC and they were very nice...APEC brand.
