I have an 84 60 with a Holley and want to return to stock carb set up. Which years will work for my truck for the carb and air cleaner? Will an Aisan carb and air cleaner off a 78 40 work? I am thinking it won't. I read the article in tech. What else will I need to get to return to a desmogged stock condition? I bought the truck this way. Thanks for your help.
