How would I measure the pulley to get my alternator fixed

Hello, I am Danny.

I have attached a picture and price for an alternator from AutoZone. If you have to pay someone shop labor prices to remove and install a pulley it might just be more cost effective to install a rebuilt alternator instead. I have also installed a couples tutorials showing how to get the belt off to remove the alternator and remove the alternator itself. Hope this helps and feel free to ask any questions.Thanks for using 2CarPros.
