I am aware of this. I ask for a stock one because I am down a truck and a bay in the shop I own both of which make me $$$$. I need this thing going and can "build" a 60 after I find one. My main thin is getting this thing rolling again. Thanksyour stock rearend isnt a dan 60! its a moddified super 44. you have to mod the dana 60 housing to get it to work, like cut the outer ends off your stocker and weld onto the dana 60 housing! i had one, i know how they are.
