Your photos show the driver side but I assume you mean the passenger side doors. If so, I made an '85 GMC that my daughter had and had to make dual hinged side doors from the sliding door of the kit. This is the under glass post of it and if you want to delve deeper here is the build thread, which is quite detailed concerning how I handled the doors. Sorry, but the things I did converting the doors are spread through the 17 pages of the tread.
here's a shot of the side doors as a quick check
I'm sure many here would like to see what you're doing with these vans.
