Air pump question

Hi all, I am new here. I have had 4 Porsches over the past fifty years and still own a '76 930 I bought in '84. The air pump froze and took out the first belt and small, 17 tooth gear on the idler. Pelican can get the belt but the gear is not available. I have located some off the shelf gears that I believe will work but I am having difficulty determining the exact pitch. It is either a 3/8 or 10 mm pitch, both very close. Does anyone know the pitch hor these gears?

The second part of my question, is do I need the air pump? This is a CA car and will need to pass the smog test. It would be great to just take this out while I have the engine out - thoughts?

Thank you for your help.
