James,
Just an FYI. I would build a FAT for you in the configuration you require at the same price (or less) than the Uni-Loc model.
My only restriction is that I can't compete with Seybert's on shafts that they carry. Since this would be a custom, I can accommodate you.
This is not something you have to move on right away. We've done business in the past and I'll take care of you on this whenever you're ready.
Have a Great Holiday Sir.
