I am looking for a set of 3.23 or 3.42 for the 12 bolt "O" rear differential that has 9 3/8 ring gear and 11" drums. I found and installed a limited slip carrier in my 73 Riv and now looking for a step up for gears. Please let me know what you may have or if you know someone else that may. Thanks Jesse
i dont know his name, but internet wide, a guy named monzaz has all things rear end, including gears etc..not sure if he is a member here or not, but i bet he is
You want something for the large 12-bolt,for the riviera and some other bigger cars. You could also check with FabCraft. They make gearsets for some of those rears as well.
