I'd start with calling directory assistance and getting Quigley's phone # if they are still in business. Most axles have an ID tag bolted to the insp. covers that. It is possible to ID the axles from that info---such as make,ratio,LS/locker. Crawl under and get the #'s before you call Q. Otherwise post those #'s here. Someone should know.
I knew Q. made 4x4 Van conversions, did not know they did duallys too. Most likely used OEM stuff.
