I have for sale or trade two very cool vintage air cleaners. They are 6" in diameter and have the smaller diameter carb necks which are 4-3/16". They fit either the WCFB carbs or the early Carter AFB's. They are in great shape, were on a '60 Corvette. These air cleaners are very hard to find. SOLD. Also, I have a trans-dapt adaptor #FE4 for a small block Chevy to early Ford trans. No cracks, or stripped holes. Looks like somebody removed a little material on the area where the starter nose would go. This will not effect anything, very minor. This adaptor is for the block-mounted style starter. Would like to trade for a pair of early Corvette valve covers with the straight-across holes in good shape for asking $100.00 for the air cleaners and $125.00 for the adaptor.
