technoprat, 205 runs 204 levers. virtually the same as 212 and interchangable, up generally with better lives. i doubt a 212 can run the 204 levers. 212 levers are obviously stronger, also they have a larger pin, or larger bolt through the pin as levers and pins can't be interchanged. looking at pics i can now see the diffs with the 412 levers.
