WTB Gear Door Mod, Air Cond, Cargo Pod

[GeneCopeland]

Thank you,
So the ship already has the Horton STOL kit installed.
Bought a used Cargo Pod from Owen Bell, I guess I need an Install kit for it also now.
Once the plane is at the Radio shop, I will buy the Gear Door Delete kit and have it taken back to Mena for Install of both pod and door kit.
I am sure the Air Conditioning will help as We live in North Texas and plan to base at GPM. From my time flying Corp Jets and old experience with big Motor 206, 210s and operation of 340s and 421s; shock cooling is an issue with the descent out of altitude, so are there any reasonable options you would recommend for Air Cond and Spoilers (air brakes)??
Also, looking for 12” N number placement options, currently has 8” on the tail booms, but looking to do a little close in International (Mexico, Beliz, Costa Rica and maybe Canada). Or are there any waivers available to 337s?
Thank you,
