I have a fox 40 bushing like the one pictured. Purchased in the early 80's (new). It is still going strong. The carb on mine is a barell type very similar to most of todays carbs. It does mount differently tho. I have a Fox pipe header for it and use a macs muffled pipe. It is not installed now so I have no numbers to give. I won't give this one up. It runs great!
