125" is the wheelbase, not 127". Maybe the 70 and older or possibly the 96-up (don't know), but from 1971-1995 your only wheelbase choices (with the exception of the cutaway box vans, I have no idea what wheelbase they were) were 110", 125" or 139".

Until mid-1996, Fullsize Chevy Vans NEVER had 6 lug wheels. The 1/2 tons (10 series) had 5 on 4 3/4" bolt pattern wheels. These are the same as most GM cars of the same era, including, but not limited to the Camaro, Malibu, Cutlass, Firebird, Grand Prix, Regal, etc.... The 3/4 tons (20 series) had 5 on 5" bolt pattern wheels. RWD Cadillacs, Fullsize Station Wagons, Some larger cars like the Olds 98 and Buick Park Avenue shared some brake parts as well as wheel sizes with these Vans. The 1 tons had 8 lug wheels. There may be some crossovers along the way (as I stated in my last reply, there were some 20 series vans with 30 series brake parts, and I forgot to mention there may well have been some 10 series vans with 20 series brake parts, sometimes depending on which engine was installed in the van), but if you find a pre-96 GM Fullsize Van with 6 lugs, I'd like to see pictures of it. The AWD Astro Van had 6 lugs and some (or most? Not really sure here) 20 Series Pickups had them as well (at least the 10 or so 4WD Pickups that I owned over the years had 6 lugs), but the Fullsize Vans had either 5 or 8 lugs until the new body style came out in mid 1996.

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?
