the other kitfox that im in the hangar with has been flying since 2002 with the data plate installed with the metal backup with no problems . i installed my data plate there and in that manor since i was having the same dar look at mine that looked at that one . its a little tight getting an arm in there but can be done . i had an inspection ring installed onthe other side but didnt want to cut it open so i did the reach around . i ended up cutting it open anyway later to change the tailwheel spring bolt.
