The AL129X which works on the 616/617s also fits the M116/117s... I have been using it on my 560 for a few years now. It is rated at 115A, stock belt works.
Yes, you can buy a 2.5" alt pulley to replace the typical stock 3". You will not find anything smaller than a 2.5" for a single v-belt. You will not overspin the alternator as the motor does not turn nearly enough RPM for that to occur.
