I got lucky and found front and rear TD's on ebay for a little over $100. Called Torklift and had them send me a new hardware kit. $46 shipped. Seemed a little steep, but it included everything. Even that bolt fisher-thing.
Granted, I got these a good year before I even had the camper and had been on the lookout for almost year previous to that. I knew that I would eventually need them. Gave me some time to rehab them with a new paintjob. Saved bunch of money. If you're not in a hurry, something will come along. Just keep your eyes peeled.
