Those snap rings can be put in 2 ways, and only one way is correct. One edge is slightly beveled, the other is sharp. The proper way to put them in is with the sharp side out, it grabs the groove better. Do it backwards and you see the results. It is amazing how many mechanics don't know this. The newer actuators with screwed in end fittings were installed in mid '78 model year P-Skymasters ( P3370298 and on), I am not sure if or when they put them in other models. The good news is you can use the newer actuators in place of the older ones if you can find them, at least in the P models. My guess is that this is true for all 1973 and later models, but I only have documentation for the P Skymaster. You could check with Cessna, or Tom Carr at CPA. Hope this helps.
