Maybe e-***. Or Google. Just make sure of distance between screws and size of shaft. Going from a 31t to a 35t will take some top end away but will add some pull to it. But if you get that pulley to open all the way it will add some of that speed back. That's why I say it would be a happy medium. Near same speeds as stock with 31t but with a bit more pull.

I'll take your insults as compliments and blame it on your lack of intelligence.
