Damn i hate to hear this....i had no idea he even had cancer....
I sold Dale a bunch of knuckle head parts about 6 years ago....he actually bought every knuckle head part i had...i had valves still brand new in the box...i had around 25 or 30 sets, cant remember the exact number....i also had cranks, cylinders and heads also.....Dale gave me more than i was wanting for all that stuff....Really great guy and my gosh so smart...
