Just for info. Our 140/180 was modified with the newer cowling. From the
paperwork and logbooks, it required a 337 (of course), but also required getting the
Piper drawings for the firewall-forward. They had to relocate everything according to
that drawing (e.g. oil cooler on the firewall with a bracket, not in front beside the
prop). Landing gear, exhaust, and maybe engine mount (not sure on that one). Lots of
redoing, and required the "approved data" of the Piper drawings... it wasn't an STC,
but a plain 337.
