belt question

[turbopwer]

I just chromed my altenator and the pulley is slightly smaller than the factory one. Now my belt is loose enough causing me to need one a little smaller. Can someonetell me the correct one to get? I'll probably be going to autozone so a part number would help.

stock listing was for the 64" belt which is too long for most cars that have replaced the alternator
try 5060635 63.5"
the 5060630 63.0" was all i could find on the shelf at advance

you might be able to order the 63.5 , i bought the last ones rockauto had
