66 cuda project begins

thanks guys, i want to make it a nice driver, maybe 360 built, sweet paint, cool rims, little rumble, and haul a** !!!!! I had a few muscle cars in my 20's, I guess this is my mid life crisis project...pulled the rear end out today, with springs and hangers, can someone id it for me. about 51" from backing plate to plate, turn yoke and both axles turn is same direction, SBP axles. If I block one axle, the other turns, (limited slip?) here is the pics...thanks again
