Thanks Leon. This bike was a box project that I bought because the bike was really cool to me. Amazingly all the parts were preserved in that box to complete the reassembly. I guess you are telling me to flip the pivot clips 180 degrees and reattach to the beehive? Thanks for catching my incorrect assembly. I also appreciate the terms you're giving me to learn so I don't sound like a rookie. I haven't ridden it very much since I put back together. Tell me what's special about the pedals?Yes. Well. In this case you are correct for a date of manufacture... but not necessarily a model year date.
Just remember that the chart you posted is not the chart... it is just a chart that somebody found and re-adapted. It was never intended to be used as DIY-ers are doing on the internet today. Never intended for J.C. Higgins...and what may be true in some circumstances for certain bicycles is not true for anything and everything that Murray-Ohio made. One size does not fit all.
Please yank those pedals and save them from destruction. They deserve preservation. Also the front Wonderide "bee-hive" fork in your pics has been re-assembled with the pivot clips backwards. EEeeeek! It was never designed to operate like this and will ultimately fail if continuously ridden this way by a present-day adult. Full turning force and suspension stress is now concentrated on the shoulder bolts. Suggest you put it back to original if riding.
