There are 2 ways to go about this, the first, use a capacitor that is the same size as the start capacitor. The other, go to a shop that specializes in electric motor repair and ask them. You might see if a business like Granger's would allow you to remove the covers from a comparable motor and get the values from that. Emerson wants you to buy, obviously, but like a lot of us, you just want to repair, which is good.
