Here is where capt., got the 7 3/4 . Add whatever you think to main firewall to make it stronger. Maybe just double it. But be sure and keep the box that ties mainfirewall to the other 2 bulkheads. What do you want? For me to do it for you? Use Stand-off if necessary between mount and main firewall. This is a lot of time dong these photos...hope you appreciate it. Capt.n
Whoa! Don't get nasty now. The picture you put in the original post was of an airplane with the engine box installed, what was I supposed to think but that was the firewall you measured. Seems sensible to me. What your depicting in this post is a bulkhead in my books. In any case I'll handle it from here,
Thank You and have a wonderful day. [sm=spinnyeyes.gif]
