Changing Required Airplanes in Missions

Hi,
I'm new to CFS 3. Learned to change airplanes in missions or rename airplanes to fly in mission in CFS/CFS2 but I'm beginning to fly CFS 3 and ran across a problem
I have one of Cliff Burgess' mission packs, Battle for Europe. His missions were always fun and even a challenge to find all the required aircraft for them in CFS/CFS2.
But I haven't yet learned to exchange or rename planes in CFS 3 to conform to missions. His BfE missions call for Herbie G's B17 mollie 3us_b_17g from AvHistory. But AvHistory only has a renamed version of this plane, AvH_US_B17G-80_001.
Questions: How do I get the renamed version to fly in these missions? How do I rename the planes in the mission files or rename the planes in the plane folders to the ones named in the mission?
Thanks for any help.
