      Paul,

      I don't think that the lower mount point will work attached to
   the nose
      gear leg.  The nose gear leg moves up and down along the firewall
   and is
      cushioned by the bungee.  Page two of the following link has a
   photo of
      the installation:
      http://www.zenithair.com/stolch801/data/gear-nose-s2.pdf

      I would feel more comfortable if we could somehow attach that top
      firewall mount point to the oil pan mount.  Is it just too tight
   to the
      firewall?  Perhaps the engine cold be moved a bit further forward to
      accomplish this.  I do not have any dimensions but the Walter LOM is
      another Chris Heintz suggested installation and the length of the
   LOM is
      substantially further forward than the Lycoming or the present
   rendition
      of the Rotary.  Here are a few pics of that installation:

      I agree. I'll think of something else. Perhaps rivet the bracket to
      the angles.
      I'll make  detail 3D of the gear leg.

      Thanks Patrick.

      Hi guys

      I need some more measurements. Here is what I need.
      You can load the jpg's  into MS Paint and mark them up and send them
      back. Or just answer the questions. What ever is easier.

   I'm out of town for the holiday, will get these to you Tuesday evening.

   As far as the top-center mount point, an option I've been considering is
   to add an arm from it to the alternator bracket mount point on top of
   the block. The conceptual equivalant of inverting the bottom oil pan to
   firewall arm that's currently used.

   The LOM engine conversion requires major modifications to the firewall
   and nosewheel. They extend the nosewheel 8 inches forward using trusses
   off the stock nosewheel channel. I've also heard that those planes act
   like lawn darts when you pull power.

   I'll review this batch of drawings today.

   No problem Kenny. Pat came through the dims I need.
   The top center mount has a caution about drilling holes so I won't use
   it.

   It looks like we can bolt the rear mount to the upper part of the
   lower channel flanges.
   Part # 8F7-2

"...The top center mount has a caution about drilling holes so I won't use
it...."

The top center mount is not optional. It is the primary load path of the
engine thrust to wing drag, through the 'windshield braces' to the main
wing spar attach points. Leaving it unattached leaves two triangle ends
unsupported. Refer to the photos I previously emailed. Refer to any of
the 'alternative engine installations' on the zenith site (including the
LOM photo I just referenced) to see the application.

Thanks for your thoughts on this matter Ken.
I gave it some thought and I came to the same conclusion at first. However it is
not totally  unsupported as the metal parts of the cowl (not to be confused with
the FG engine cowl) in shear and firewall sheet metal are the support. The cowl
sheet metal supports it in the horizontal  plain and the firewall partially
in the horizontal plain but mostly in the vertical plain. Both provide
support in the lateral plain. The problem with an upper horizontal strut
to this point is it interferes with the intake manifold and or water pump.

If after you have your engine installed and the intake manifold finished
you could add a strut with rubber rod ends to the upper fifth mounting point.
It would not hurt.
