I have a set of heavy duty axles with 5/8 studs and bearings for an 8 3/4 rear out of my 72 Cuda. I was told that these were Moser or Strange axles when I bought the car but there is no definate markings. I've been told these might be Mopar performance axles from back in the day? Either way these are some very nice beefy aftermarket axles! $150.00 plus the ride
