That is weird. You could release the three bent over clips (picture below) and pull the axles, leaving the sealing plate behind. Maybe you'll find something odd. Maybe they fastened the sealing plate on then assembled the CV afterward. People do strange things, like they did on your inboard CV. I posted a link to where my earlier picture came from that showed a source for the axles. They were used on 2+2 280ZX's or turbo 280ZX's. They're hard to find and sometimes the aftermarket parts are different. If you find one at a parts store take your old one to compare lengths. https://picclick.com/2x-CV-Joint-Axle-Assembly-Rear-Fits Datsun-280ZX-253130612896.html
