Parts Needed for Grubee Honda Build

I know I really should have bought the whole kit back when they were available, but I didn't. After buying my Honda GXH50 motor, I ended up buying a Grubee Gearbox to go with it. LONG STORY SHORT... I would be interested in any associated parts you might have which are surplus to your needs... Muffler, tank, sprocket, mount parts, throttle... What-have-you. I'm hoping somebody will have such parts they're not using. Please let me know. Thanks.
