How many and what size alternator bushings do I need?

[Chapel]

My alt bushings are toast. I ate one belt and threw another last week and upon inspection found the alternator bushings were hosed.
I went to buy some poly bushings but they are listed as 'large' and 'small'
do I need 2 of each or what?
I plan on getting it fixed over the weekend

On bav auto they only list one size which I believe are the large and it says 4 are required. I just bought them and will be installing them soon. I'll let you know for sure when I'm done.
