Gears & Axles - moser 12 bolt,what size u-joints

i picked up a moser 12 bolt and i noticed the rear u-joint is a different size and the strap to hold the u joint down is different also,does anybody know where i can get these parts,or have a part number the car is a 2000 camaro with a 6 speed ,thanks

It probably has a 1350 yoke and if you're going to use the stock driveshaft you'll need a Napa 447 u joint. Bob
