[f-AA] Wing questions

Aeroncateers

A few questions on the wings.
1/ How is the leading edge stiffener P/N 7-439 fastened to the ribs? I 
fancy it may have just been held there with a piece of anti friction 
tape, but it's so long ago!!
2/ On my drawing 7-439 which is for the later Champs I guess, there are 
four blocks P/N 1-10024 shown as nailed to the top of the inner end of 
the main spar, what are they for? I don't think there were any on my 
1947 Chief.
