yES WE CAN MAChine the cones and is fairly cost effective as long as your spider gears are good we should be able to bring the posi back to life again. Usually 150.00 plus the shipping. That is worse case on the cones. BUT if one cone is bottomed out the other is probably niot far away. 50.00 per side and 50 to clean disassemble and reassemble if you want the break down. Jim
NEW units are Auburn 429.00 Eaton 449.00 Both are very good and will be a great upgrade from stock. What ratio are you running ion the rear end? Jim

Was told by a fellow member that you rebuild the cones on 8.2 10 bolt units how cost effective is that or would I be better off just swapping to a eaton or Richmond thanks for any help in advance
