Dew, those 69 pipes may not be correct for that Serial # range. If there is a notch under the brake pedal, they are not correct for early sandcast..
While I agree with a lot of what you say, you may be overlooking HOW HIGH the Demand is for true sandcast parts..
Maybe a bit easier to understand this way.. If you have a Ducati Mach 1 tank or frame or clipons (I mean correct stuff), the supply is small, and people in the Know that have the stuff , are not giving it away cheap..
I am thinking a trip to that place I got my early sandcast from, is in order, I did not get the pipes, they were in a shed full of wood.. might still be there..
