Convert Sturmey-Archer AW hub to AWC I have a 1972 Schwinn Breeze with a Sturmey Archer AW 3-speed hub (no coaster brake).  I would like to replace the internals of the AW hub with the internals of an AWC hub (which has a coaster brake).

Is this conversion possible without replacing the outer casing of the AW hub?  Not sure if the two hubs have interchangeable internals.
My AWC hub was incompatible with AW hubs.
I find re-spoking much easier than working inside 3-speed hubs.
I left those 3-speed bikes behind at a beach house, but based on memory:
- AWC internals are removed from the coaster brake side, while
- AW internals are removed from the sprocket side.

3-speed hubs that I disassembled seemed beyond repair,
but to help reach your own conclusions about relative difficulty,
this video seems representative:
