I think you are just doing this for grins, since you have a direct drive assembly to mount.

I went down a similar path, although not nearly as industrious. What I discovered was that the blower housing acts as a huge sound resonator. Even though the new bracket stopped the belt noise, the low frequency vibration of the motor, and also of the bearings still rumbled through the coach. The point is not been there done that, the point is that while you working on this, find some way of isolating the motor mount vibration wise from the blower housing. I really do think this a big reason the direct drive is so much quieter, that the motor is hung from the center mounts, and the center mounts have a rubber isolator between them and the blower housing.

BTW, I am really glad you are here. These guys have been busting my chops about my welding for years. I am happy to have the company.
