The GCR states:

"a. Any final drive ratio is permitted provided it fits the stock differential/transaxle housing without modification to the housing."

Now, do we collectively take this to mean any ratio, meaning, any ring and pinion of any shape and size, as long as it fits in the factory housing? So one could use a ring and pinion out of unobtainium, a skeletonized ring and pinion, or one that wasn't based on the factory OEM gears at all but fit into the housing?
