Jerry,
On the top of that page or the other one that shows that I also was
looking and if you hold the plans just right you can see that there
is a 45* on the 697. I also found out that if you cut the 45 it will help
but I had to trim mine to 87.25* (JUST KIDDING). I did just trim to fit
after the release was catching on that. You will also find that you will
have to trim the hole 1/2 x 1 inch a little bit too.
Keep pounding those rivets.
