what do i have , is this an early 10 bolt that has the removable center section like a ford 9"? is there posi's and lower gears availible for these, and where can i find one? how strong are they? what can they handle? this is in a 61 buick hearse its the same length as an electra, its not stretched, i have a dynaflow and 401, its soon to get a big cam headers and a 2x4 setup. what gear would be good for this set up? also will be switching over to a power dual cylinder brake system soon it has power without a resivor right now. and hopefully one day i'll get a 400 trans in her but for now i have a dynaflow because its not an easy fix being a 61 block
