WANTED: aftermarket locker or stock Trac Lock for a D60

[Lonesome7.3]

I need a reliable traction aid for my 72 D200 build. It has a Dana 60 with 4:10 gears and 30 spine axles. All I need is a good used Trac Lock posi unit. But if the deal is right I might be interested in something different. Let me know what you have and we can go from there.
