Not sure if it helps or not, but none of those look like the one on my parts 76 F.
the 2nd from left is most similar, mine has a double bend in it right where it goes under the peg
from the pivot at the frame it goes about 6 inches, bends down and to the right, then about two inches it it bends up and to the left, crossing right under the pivot point on the peg.
If you need actual measurements or pics, I'll send them.
Ken.
edit: just realized this was regarding a potential on-board sale....
