Been combing the parts manual for my '75 Arrow trying to find correct screws for mounting aileron to wing. Mine are slightly rusty and because I may be removing the ailerons for hinge replacement and would like to replace all that old hardware.
These are the slotted head screws that I THINK are also used for the flaps. It appears as if they are 10/32 AN525 'washer head' screws, but without taking one out or finding it in the parts manual can't figure the grip length.
Anyone know off hand what the MS number and length are? The nuts appear to be standard 10/32 AN365 lock nuts.
Thanks in advance.
Joe
