The horizontal channel (z-bend) is 110mm wide.  The short flange
attaches to to the middle mounting points and the 110mm flange ends up
at 450mm above the bottom of the firewall.

Here is the link to the build manual section that provides some more
detail:

It may be a bit difficult to get the frame members that attach to the
middle mount points to clear the z-bend

OK Pat. Thanks
