Rebuilt my 7.25 rear end and bad news....

good luck finding new parts for your 7.25 rear end. most people swap out to an 8.25 or 8.75 instead of messing with rebuilding the little one. If that is not an option for you, i've got an exploded one in the backyard that I might be able to take apart for you. it wasn't making noise when I blew it up. I think that the spider gears are toasted in it, I haven't opened it up. I just chucked it out next to the shed and put in an 8.75 instead.
