I called Move Bumpers and talked to Kathy...Here are a few details.
Steel DIY bumper kits are $395+shipping. They apparently are multi-piece bent/formed 3/16" thick steel that require welding and painting or powder coating. You use your vehicle as the fixture.
They can also do aluminum kits for $595+shipping.
Fully finished bumpers are $1295......
Here are a few renderings that Kathy emailed me; the pictures on their website are from customers....so far no van customers have sent her pictures. I'm assuming the front bumper with grill protection is more $$. Also looks like the front bumper is for 1992-2007 only.
