I am in need of a air boot for the 74 250 harescrambler I am rebuilding. It has a lectron carb and the air boot that is on it is the offset style you described as fitting the 76 models. I would be interested in ordering with you. I have gone to their website but I can't get the link that shows their rubber products to load. Let me know when you are going to order and I will send you payment. My email is [email protected]. Thanks, Terry
