WHEN ORDERING - PLEASE NOTE YOUR AIRCRAFT TYPE, SERIAL NUMBER OR "N" NUMBER IN THE "NOTES" SECTION. WHEN ORDERING - On ALL PA28/32 there are two different combinations of Bolts/Nuts.  Prior to the late 1980's to early 1990's the Bolts were AN176-13A and the Nuts were MS21045-6.  Piper decided to change this combination to NAS6606-13 Bolts and MS21042-6 Nuts.  Both Sets are Close Tolerance Bolts with the same diameter, with the "New" Bolts are a little bit shorter.  You can tell which Bolts you have by looking at the Main Spar from above: the "Old" Bolt Heads are Flush; the "New" Bolts have a Concave Head.  From under the Wing/Fuselege - The "Old" Nuts require a 9/16" Wrench/Socket; the "New" Nuts require a 7/16" Wrench/Socket. When Ordering the Kit - in the NOTES Section indicate either "OLD" or "NEW" Bolt/Nut combination.  If nothing is indicated - we will ship the "OLD" Set. Kit consists of the following: 4 - AN176-13A (NAS6606-13) Bolt, Close Tolerance - 3/8-24; 4 - 96352-003 (494-2
