Don, I think the correct part number from Skyport is FMK 2 Wing Attach Hardware - both sides, front and rear.....$53.95. their order # is 1-800-624-5312. Tech support # s are 414-534-4233, 2395.
Univair will also have the parts. tel # 303-375-8882 fax 8888 I had thought these were special clearance bolts, but that may not be correct. Might be worth checking on, tho. The close tolerance bolts assure a tight fit with no play, where as a standard bolt of the correct diameter and length may be too loose a fit in the attachment holes, allowing the wing to have some play. This would only get worse and maybe cause a fatigue failure. The bolts are in shear, not in tension. However the proper torque prevents the wing attachment plates from having clearance and rattle..... Harry.
