The final drive housing is cast different as the shock mounts are at slightly different angles.
It also won't bolt up to our swingarm.
The guts are interchangeble though.
I'm not so sure
all the stuff inside (guts) is interchangeable.

It's not. I attempted to use parts from a GW Final in the Valk. The ring gear & pinion are different. The driven flange is the same, perhaps some of the bearings, but the parts most need, are not. Different part #'s, different bearing sizes on the ring gear.
Interesting. When one of the guys around here had his go out, they cross referenced the ring gear and pinion to the 1500 Gold Wing rear end.
I do know that the drive flange cup and the driven star hub are the same because we've used those parts from a Wing rear drive to rehabilitate a Valk rear drive.
I wonder if the GW parts, if not interchangeable, would still fit correctly in the Valk case? In other words, could you just take all the GW parts and transfer them.
