Re: 1966 C-10 Rear End

3.73:1 was the factory 12 bolt rear end installed in the '64-'66 Chevy C10 series trucks. I have purchased a 3.08:1 posi on eBay and I see them on there frequently. They sell the entire master set up kit. I think I paid in the neighborhood of $375-$400, plus shipping. Do a search for 1966 Chevy Truck and check the search Title and Description box. There will be 1,500-1,800 auction items results. Sift through them and you will find one. Good luck with your gear swap.
