Drawing number is the same as the part number and available in the free parts manual on Univair's website. https://www.univair.com/content/partcatalog/12PM-flipbook/mobile/index.html#p=23I am not sure what it is.
I didn't like the fluted flange on the titanium firewall I got from Atlee Dodge s
That Atlee firewall sure looks nice, do you have a drawing you use for making the recess in the lower boot cowl? My skins don't line up very well where the sides meet the bottom.
I’ve got a new Atlee stainless firewall on my airplane with a new boot cowl. The project came with Atlee PA-18 style L brackets. I had to modify the support brackets to accept them. The airplane has the Studdard short mount which required the forward part of the brackets to be trimmed too...that was done in 1968. As far as I know this airplane hasn’t flown since the 70’s. Hopefully, be back in the air this summer. 820 hours TTAF.
For those of you who have replaced the firewall. Do you run the cables higher or lower like original? I’ve seen some that have a fairly clean lower interior firewall and assume those cable penetrations are higher. Also, do you like the 2 piece firewall brackets or just use grommets?
