can anyone tell if there are stock shafts?

[hurt4x4]

the guy i bought the jeep from said there where "nitro" shafts but i have no way of really telling, I was just wondering if they look aftermarket or not and im really not expearenced enough to know. there is no markings on them either. they are out of a hp30

the stub shaft looks aftermarket due to the are between the seal and the u-joint looks turned down instead or raw steel.

They look like Nitro to me. Do they have full cir-clips? Or at least machined for them? Can't tell from the pics.

they do have full circle clips, and the 2 pieces of the shaft are actually hitting each other when the wheels are turned all the way? that seems like it could cause problems
