Default Reared slipping magnum 325

Rearend slipping on 325 magnummy bike will not move under its own power when I put it in gear I can push it the drive shaft does not move but it makes a clicking type of sound . I jacked it up and turned the wheels while it was in gear it made the sound and looking down on the prop shaft coupling so I could see he grease nipple it did not move. I took the rear axle assembly off and the connections between the coupling and the pinion shaft seemed to be in good shape I then split the rear housing and looked at the gears . At this point I should tell you I don't have a clue what I am doing. So I took some pictures and hope someone can tell me if they are worn out parts

It seems the ring gear is slipping on the axle

Have seen several of that style do a similar thing but it's where the pinion gear and driveshaft(between the trans and gearcase) the splines are worn excessively and spin under load.
