I don’t know how to explain it well but here it is from

Parts not found on the plan: Any response appreciated
All files printed out and reviewed again and there does not appear to be F4a or F4b on the plans? In the build guide on the first page pic 2, can not find any of those parts? Where are the "left and rtight lower" pic 2 again
