Ph1 172 Alternator pulley HELP!!!!

[MADVALVER]

Help, Im in the middle of changing the AUX belt on my 2000 172(A/C model), and found the reason for the belt being chewed up. The alternator pulley is bent, and cracked on the outer edge(WTF) and needs replacing.

Would really like to get the job finished tomorrow, so has any one got any ideas what pulleys from other cars will fit if i can not find another 172 alternator or pulley.

Hope to get some work in progress pics up soon,

Thanks

Brian
