I was told the same, Noma went out of business a long time age. Little to no parts available. How big is your mower deck? Model #s don't mean anything to me, not a dealer.
I am scrapping out 5 old riding mowers. May have what you need. I think I have a like new spindle for a noma mower deck. The deck is cracked and junk. Hope I didn't send it to the recyclers.
My email is open, send me some pics of what you need, I'll see if I have what you need.
The gray noma I put a craftsman mower deck on it and the red one has been ridden hard and put away wet, even went through a fire.
