I own the same year, I picked up a beautiful seat at a swap meet that even had the crome trim still
intack for $100. Ebay should be your last resort, its an auction that drives up the price and the seller is miles away so they don't give a damn about ripping you off. I got burned on Evil Bay. David Silver is good but they are running out of stock. I bought a new OEM set of stock exhaust for my K4 from Classic Motorcycle Supply in the Netherlands, google CMSNL. The pipes set me back a grand, they look awsome. I may be selling my 74 in the near future. I'm in need of a car. Good luck
I can see November from my house
