I'm not sure about the "plans" part but we've had two guys write about it for us in the Tech Tips.
One by Mark Marmon for his 1959 Apache.
And one of our favorites, with step by step instructions
by Irwin "arnswine" Arnstein -- "Where's the fun in that?" -- for his 1959 1-ton.
Irwin is easy to get hold of and I'm sure he'd be glad to give you some additional tips.
See if those help - at least a start. It is DO-ABLE.
