I got one from Combine World last year. With rims, and hydraulic cylinders, everything from the pivot tube back, less tires. Cost was $2200 plus about $120 freight. Their phone n is 800-667-4515.
I have a complete one off of my 98 C62, axle is the same as an R62. It's complete with good 14.9 x 24 wheels and tires if you need them. let me know if you are interested.
