Why is it that Mechanair can build a dynofocal mount to the rear plate
on theirs, and it doesn't work on the 13b?  I think general acceptance
of the 13b would come much sooner if we could make the 13b  a bolt on
replacement for the 0-320 and O-360.  Of course there are lots of
systems that have to be replaced (radiators, ignition, electrics, etc
etc) but the bolt on to the same mount, putting the prop flange in the
same place as the O-360 sure would help...

Besides, it would make my life easier when I want to put a 13b in my
Cozy.... :-)

The whole rear cover is an entirely different casting. Read big bucks.
Actually I think they should start selling that kind of stuff
including the bell housing and the PSRU.
Good for us and good for them as it would generate a bit
of immediate cash flow for them.

Bad Idea.  When you put a 13B in a plane designed for a Lic, you need to
move the whole thing back toward the firewall to make the prop set in the
same place.  That way, the w/b will come out right.

My plane with the water pump hub 4" from the fire wall worked out almost
exactly the w/b of a similar ship with a Lic.  It has a 14" Ross on the
front.  I moved the dynofocal hubs back about 8" to achieve Tracy's mount.

I'll pass too. Too heavy and too expensive. Why pay $65 to $200 each for
four  Lyc rubber bushings when two at $8 each work fine. 
Motor mount design is not that big a deal.
