Hey everyone. First off. Great forum here. I just bought a new to me 1978 Arrow three. I love it! But it needed some Tlc and I just got the cowls repainted and repaired. My question is the Piper parts manual shows regular screws and washers holding the bottom cowl to the firewall. The screws that came off were 100 degree washers with SS Phillips in them. Which screw combination Is Factory?? Are the 100 degree washers added because the holes are so beat up? Thanks in advance.
