I have a full Jeepster Commando boxed frame w/ tranny, Xfer case, axles, etc just waiting for a wagon body. Set and ready for a 304. I don't think a solid frame swap could get any easier than this. The wheel base and width is perfect. I believe the Jeepster wheel base is 1.5" longer than the wagon's so with a very mild spring lift it will be bang on.
Shanebo, this is what I currently have planned for the blue wagon I picked up from you. Unless someone wants the frame, I'll use it when the time comes.
