I have spindles but I do not have the timed pulleys. That's why I am looking for another complete set up. I want to 'Americanize' it where if I needed parts again they were readily available. If I find another set up I will be more than glad to sell you the spindles I do have.
600 bucks is quite a bit for a deck. You could about buy the metal, spindles and blades to fabricate a deck for that much.
One of the chains for the steering was missing on mine and I just fabricated that up. If you ever have to make one of those use #35 chain and 5/16 square stock. That's how I made mine. I didn't use master links so sometimes popping the pins in and out became a pain in the rear.
