89 Marathon

[granprix]

I just acquired an '89 Marathon gas. The driven clutch is bent and cracked. so I removed it from the shaft. After removing the clutch, the imput shaft has alot of play (appx)\ 3/16" in any direction. i found a seal sticking out around the pully and I removed that then removed the retaining ring but the imput shaft won't come out. 3 questions: where can I find a used driven clutch, How do I get the imput shaft out, is my problem bigger than the value of the cart? The general condition is the cart is poor, its been sitting for 5 years. It looks like a rag and it needs tires. The starter works and I did get the engine started after a complete fuel system cleaning. The engine has 150 compression cold. Is it worth it or not??
