Parts for your 1990 scag mower

[tschwarting]

There's a company here in NY called Newburgh Power Equipment and they have an AMAZING collection of parts. You'd go absolutely NUTS looking around. Their telephone number is 845 564 6960. You can text them at 845 492 9652. Or you can email them http://www.newburghpower.com.
I'd be surprised if they couldn't help you. Good luck!
