Douglas, I have the adapter for my carb in my garage, it is different sizes at both ends. It is a reducer to go from 1 pipe size to another. I found a stock 37 air cleaner that fits without it, so it is collecting dust in my garage. If you can use it, you can have it. I'll have to measure the sizes. Winchester stocks lots of them in different sizes at both ends and can order sizes not in stock. I'll measure mine. If you want it, contact me @
