What is a ball park figure for how much it will cost to rebuild a corporate 14 bolt? I am getting one off of a 1976 Chevy 3/4 ton pickup for my 1974 Jimmy and would like to go ahead and put new seals and everything in it before I install it in my truck. I haven't ran the numbers to find out the gear ratio yet but I'm hoping for 4.56 or 4.10. If anyone had any info on that it would also be helpfull. I appreciate any info anyone might have, thanks.
