On the Piper Drawing 12365 'Firewall Assembly' it shows four 'reinforcement' patches Part number 10792-3.
I'm not seeing them in any of my parts. I will add it to my ask Jay list but if someone has already checked into it or knows something more.
Also, it probably doesn't matter with a blank firewall but it looks like the stiffener beads bump out on the forward side of firewall correct? I have seen a few cub images with them on the inside but looks like most are bumped out to the front (and cross-section A-A looks like it means forward)
I thought it made more sense to have them pointing back so the flange would rest flat against the firewall when riveting - but that is moot since the top and bottom are on opposite sides of the boot cowl flange anyway.
