With all this talk of dana 60's I got worried supplies might run low so I nabbed one off craigslist for $100. My understanding is it came out of a 77 F250. After 2 hrs of hammering the 80lbs of drums are gone and I'm ready to start cutting into this mammoth. I don't know if I'll run it next year but it will be ready. I figure all in it will cost $850 if I reuse my CPP rear discs.
