Predator Carburetor Wanted

I remember going to the Street Machine Nationals in the 80's and these were brand new, I actually have a Predator key chain that my duster keys are on, I found a place on-line that you can get rebuild parts and NEW carbs boy they are pricey. I am sure you looked on Ebay, I didnt find any used/rebuildable ones on there, good luck with your search wish I could help you.
