Door / window differences - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1970 Chevy C20 Custom Camper. When I got the truck, it came with a second set of doors. I think they second set may had been the originals. I am playing around with door alignment, and it seems like the doors that are on the truck now are shorter at the rear than they are at the front.

I measured the doors on the truck now, and they are 17-1/8 at the wing, and about 16-7/8 before the curve starts.

I measured the spare set of doors and they are 17-1/8 from the wing to where the curve starts.

So what doors do I have on my truck now? Different year? Suburban?

I don't believe there was any different doors. I think what you are talking about is the precision fit of old cars and trucks! LOL When I think of the difference in fit and finish of my 1965 Buick compared to a 2018 Honda Civic holy crap! I had to cut and weld piece on my 65 Buicks ORIGINAL panels that came with it from the factory to make them fit "decent" and how I can throw a fender from across the room onto a 2018 Chevy Cruz and it would fit better, I have to laugh.

I got doors from who knows where (I can't remember what I did yesterday let alone 25 years ago) on my 48 AD. They are 47 to 51, and off different trucks. Ok, one is a quarter inch longer at the body line below the window! A quarter inch! Todays cars we are talking a few thousands of an inch at most! These are the "same" doors!

Nope, I am thinking your doors are simply not perfect, but not off different models or anything like that.

Thank you. That is incredible how far off a factory piece can be. Even 80's K car stuff I've worked with has been pretty much bolt up and go.

I was doing a bit of looking around. Only difference I saw was in the '72 doors, and it was not related to the window frame.

A bit of history. The truck was originally owned by my grandparent's neighbor. My aunts and uncles knew him growing up. In 1987, my uncle bought the truck. My uncle gave me the truck in 2010 before he passed away in 2011.

I started asking around about the door. Asked my father and a friend of that family that was always helping my uncle with the truck. They both say the doors on the truck are the originals.

Guess it doesn't matter too much. Just got to get them to close good enough that they don't leak.
