Going to do more research. Those two pictures above from a google search. I don't want to go crazy on the build, won't get anything else done. Stand off, OK, if there is still such a thing.
I found rocker covers on horizons site. I can make the dummy rear cylinders, then use the stock covers that are like the real thing. This 90T due in about 7 days, coming UPS from Poland.

Got the Cub box out last evening, digested the instruction book. Kind of straight forward, no issues, just build the cabin, then the rest. There is some good threads on this build.
Thanks Nausert and all for comments. Heres the real thing, and my J-3 from the past.
