Okay, so I grabbed some other parts and set it up to rotate.
There are 2 "L" sections and a short chunk that slips into the ends. These provided a footprint that was longer than the van sideways.


I also removed the wheels front and rear.


We then lifted the pivot points and locked the van higher and presto! It's sideways!~


This makes it a lot easier to work on the roof and other sections for my buddy, the painter.

I also was able to start getting all the dirt out of the underside. That is a big problem on an older southwestern car...
