Paul,
        Thanks for the input.  The landing gear pivot bolt is a 1/2" stud that
secures the main gear by trapping it between two bulkheads like the Cozy
MkIV.  The rear hard point is boxed from the firewall to the rear landing
gear bulkhead.  Exhaust: What is the space required for the tightest SS
tubing used for the exhaust?  There is room.  Rear mounts: What size tubing
is used to support the isolators?  It looks like 1" very short stub with
just enough length that the tubes have something to weld to.  I am assuming
that the arrangement in the pics for the rear mount will not work?

Generally speaking a 3 inch center line radius is about
the sharpest radius you can find. That makes fitting the
exhaust into this type mount rather difficult even using
two inch exhaust SS tubing. It is also not good to have
a sharp radius as soon as you exit the exhaust ports as
that is a good way to burn a hole in the bend.

Here is a 3D. I will see what I can do to fit in some exhaust
tubing tomorrow as I need to go pick up some manifolds from
the machine shop today. This could be a big waste of time unless
we plan ahead carefully and make sure everything fits.

What is the distance from the lower firewall hard point
to the upper firewall hard point?
