They are very strange looking. There's almost enough room for another door behind the side door to the rear wheel.

<strong> The 3 wheelbases were 110", 125" and 139" (139" came late in the model life of the 2nd gen GM vans)</strong>

These 139" vans are probably the rarest chevy van out there. Dont count on finding one of these. I think the mid length is actually 127...mabey, Im not sure on that one.

<strong> The easiest way to tell them apart...
The 1/2 tons had car brakes, and car wheels would fit on them (I had IROC wheels on one G-10 I owned). The 3/4 ton had truck brakes. Car wheels will not fit on them (except for big cars like the old Caddy and the big GM station wagons). The one ton had 8 lug rims. </strong>

Not true. All half tons from the factory were 5 on 5, as well as 3/4 ton. Your van must have had some custom work done at one time. And not all one tons were 8 lug, actually most are 6.

<strong> I believe 78 started the side door and 85 started the front doors with the added body lines (but don't quote me on those dates). The rear doors also had a license plate pocket on early models...</strong>

You're a year fast there. It was started on the body in 77, door in 84. Licence plate was moved to bumper in 78.

<strong> Steering colums changed in 78 to include the key in the column (prior to that, the key was in the dash). </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Not all were in the column, some 78+ were still in the dash.

I dont mean to be blunt or rude, just adding to/correcting some little things I noticed. I didnt know about the windshields though.

Another interesting fact: the slider rail covers were screwed AND spot welded on until sometime in the late 70's/early 80's, then just screwed. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">I'm sorry, but I'm finding myself disagreeing with most of your disagreements. I know for a fact that the body lines in the side doors started in 1978, not 1977 (all parts books list 1971-1977 for early and 1978-up for late. Besides, I've owned both years of vans, so I know for sure.) and the lines in the front doors started in 1985, same year as the taillight and side marker light design change. I owned a body shop for over 25 years and worked on literally hundreds of Chevy Vans over that time (as well as owned dozens of them from 1967-up). I do not claim to know everything, but I know what I know.

Do you mind if I use your posts to fill out the Wikipedia article on Chevy vans?

Hey, I found a picture of a 139" wheelbase van and it was right on this forum, as an avatar.....

Look at the the avatar in this post:

Can I put doors from a 1993 Chevy van on a 1977 Chevy van ?

Yes you can ,I have 95 doors on my 73 g20.

Doors are solid except for crease dent on driver's side,the guy tried to take them off before I got there.
