[amsat-bb] Aluma Tower and Yaesu G5400 Azimuth Rotor

Hi; I am in the market for an Aluma Tower T-40H, I found one which needs a few parts and DLC, (anyone else selling similar in Florida, speak up). My question is the installation of the G5400 azimuth rotor. I didn't have the tower and rotor in same place at same time, so I made up a 7 1/2" diameter template simulating the bolt hole placement and outer "corners" of the bolt bosses on the rotor bell. It seems that it "might just fit" with about 1/16 inch uncertainty. Has anyone else installed this rotor inside of an Aluma Tower T-40H? Some say it interferes with fully retracting with some rotors. Experience good or bad, please share.

Thanks
