thanks every one its no big deal im gonna do mini tubs at some point that will net me some extra space, but the main reason i wanted to kinda skid by is i have a factory option posi unit in my truck. I have not taken the diff cover off or simply jacked up the rear diff and spun the tires on the parts truck yet. Its good to know the different widths in years thanks guys. Depending on the out come ill probably just buy a pair of after market axles. $289 for 2 new 5 lug axles isnt too bad, then ill just use 71-72 drums and i will be golden if the other unit is not a posi. btw the truck is a 68 its a roller with 6 rubber maid tubs of parts lol. its a short bed step side with a disc brakes up front, i dont trust the booster and prop valve where swapped from the disc brake truck they used so im gonna get new ones of thoose as well as a 71-72 brake pedal to booster rod.
