Also do a search on quigley but I think the closest quigley place in in CA. Try clydsdale also. And then there are a bunch of the small time 4x shops around.
Don't know if you've seen these or not. There's a ton of good pics. Also i have several pics of my '85 1Ton....but she's a beater.
Anyway contact me if interested.
There is a guy doing the conversion now that frequents this site drives/goes by "warwagon" look him up also he is doing a conversion this winter. He might be able to kick in some ideas.
Good luck.
