i have a set of 4.10's in my 70 chevelle 12 bolt that i would like to trade for a set of 3.55's or 3.42's. I sold my 6spd and and need a little less gear in the rear. I believe they are richmond gears. i also have the auburn pro diff that i would no longer be able to use. so if you have a 3.55 or 3.42 rear end setup with an eaton or auburn setup and want to swap over to a 4.10 setup, hit me up. these parts only have about 5000 miles on them. If there are no takers soon ill just order new stuff and put my old stuff in the classifieds...
