     To service the bungees, would the bracket have to be removed and the
     rear of the engine supported?  That is the only downside I can see.
     And I don't know how big of a deal that is.    On the other hand,
      this solution is strong and light and has a good strut angle.  Jerry


         ---------------------------------------------------
         This is what I suggest. A couple of simple 4130 sheet metal .090
         thick brackets bolted
         to the lower channel and fire wall with 10-32 machine screws. It
         also picks
         up the 3/4 inch diameter bungee cord pin where all the landing
         gear vertical
         loads are applied to. That pin, with the aid of the bungee
         cords, supports the
         entire weight of the nose of the aircraft while on the ground or
         impacting
         the ground :)

         What do you think?

Looks good, I like it. Servicing the bungee is a major undertaking in
any event; I don't see this making it much worse. It may even help, as
the brackets could be used as a leverage point to stretch the bungee
into position.

The bungee 'fills' the channel behind the strut completely, there's a
good chance of it rubbing against the screws during taxi. The screws
would need to be applied from the inside out, or maybe SS rivets could
be substituted.

Here is the screw I would use.

Here is a pattern on the rear MM bracket and a top view dwg so one can bend
it accurately.
