74 power wagon dream truck...
j par I have been watching and admiring your truck build for awhile. Nice work! When it comes to suspension one person I would consult with is Craig "Radio" Wolka. He use to work for Carli Suspension and owns a '74 Dodge 3/4 ton I believe. Last time I talked to customer service at Carli I asked about Radio and they said he left and now is working in Spokane, WA. They should give you his contact info.
I use own a '78 Power Wagon and one the best mods I did to that truck ws bolting on a factory step bumper from a '92 3/4 ton diesel. Made working on my truck a lot easier. Keep up the good work.
