The clock in my Baron yoke is old, scratched, and otherwise doesn't match
the new interior. The only one available that might fit is a Davtron, which
is not approved by STC.

Therefore, it sounds like I need a 337 and a field approval to install this
clock. Has anyone had a similar experience? It seems like a lot of hassle
for just a clock, although it is a permanent installation, etc.

Any suggestions?
