Right now I have the orignal, lousy rearend with drum brakes. I would like to get a moser 9" made to 4th gen specs so I can get rid of the spacers. I also wanna get the baer track kit, and was wondering if that will fit on both the stock rear end and the moser. In other words will I be able to simply take the brakes off my stock rear and slap them on the 9", or are they different in anyway? Thanks
