Finally found it"
What Kit are You building? in your post it sounds like the US 60 was an ARF and used as an example.

one other thing, if possible make a copy of the plans and what I have done before is lightly spray the plans with 3M77 and put the clear painters plastic (.97@wally world) on the copy(little extra work but helps. You never Know who wants plans down the road.
