That is an older body style van than what I worked on as atm vans when I turned wrenches for a paycheck.
On the vans I worked on the front glass was 2 pieces with a strength brace in the center of the windsheild to help brace the glass. The glass was super thick.
Those vans were no where close to bullet resistant in all areas. No way to do that on a one ton chassis with cheap materials, well cheap when it comes to atm vans and bullet resistant stuff anyway.
The front suspension was what I beefed up and these were brand new and converted vans. We order the heaviest rate coil springs we could get, custom order and place would not build anything with a higher weight rating for us. And that was just a start. We also put an air bag in each coil spring, like the firestone bags and what not, and set them up so we could air each one up seperately.
When my co-worker did the alignment he used air pressure to set part of the front alignment and we put a sticker on the van with the air pressure numbers needed for us to set the alignment. They generally fell into a similar area but each van was a bit different.
I typed all that out to simply point out that while I don't know exactly what all that van has, atm vans are often overloaded on the front suspension and while we could get decent tire wear and handling out of the thing the methods we used to accomplish it were odd to say the least.
I liked having them to work on and learn about but after seeing them in person and crawling around on one a bit working on it I was not astounded by it once it left the shop.
They are what they are.
