Van vs. pickup vx. blazer frames - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So, can anyone tell me if a van frame/chassis would match up with a blazer tub?

I know it is an odd question, but I saw a 72 van, complete and a blazer tub. Brought interesting thoughts to mind.

Thanks

Those vans are unibody.

blazer frames are shorter than any pickup frame

1972 vans do have a full frame. they are all leaf springs >if i remember correct they are a little wider then the truck frames but may be wrong on this

this may be some help

As stated vans are uni-body, frame is welded to body.

I don't know where you get this info? It's not true.

All Chevy/GMC vans from 1965-now have a full frame.

actually IMO it's a matter of what you call a unibody. Their is a frame and it is welded to the body. To me a unibody the suspension components are bolted to sheet metal like a mustang. T-Birds were advertsised as a unibody in the late 50's and 60's. They had a frame that was weak between the wheels and ran inside the rockers. Thats why they always broke in half when they rusted out. ANyhow a van Frame would not be much use without a lot of mods. So yes it is a unibody but it is built on a frame. The larger one tons had a frame. So yes blazer1970 you are correct.

I get my info from owning a '79 GMC 35 [1 ton] 4x4 van [Pathfinder], the frame is welded to the body. This makes it a unit-body [uni-body], this means the body DOES NOT unbolt from the frame. If you think I am full of **** you should take a walk through your local wrecking yard and see for yourself. Do your homework before posting incorrect information. I have owned other GM vans from the '70's/80's as well as working on countless numbers of these GM full size vans and everyone of them including an '84 Chevy motorhome I stripped down and put a '46 Chevy COE on were uni-body.
