I've been looking into the 10 inch drums, for a couple of days now. If I understand the objective correctly, at a minimum, we need to find a 10 inch drum with a 5x4-1/2 bolt pattern, which is deep-enough (2 + inches of working surface). While the rest (center hub hole and the total depth) can be adjusted at a place with a large lathe. Is that right?
Here are a couple of quick options I found:

The first one has a smaller center hole and bolt holes, than the second one.
Does anyone have a 10 inch OEM drum to play around with, to approximate how these will fit? All of my are currently installed on the car, but I would sure like to procure some spare drums for future use
