We just started work on a 74 Comet, 302. The Fresh Air intake kit is missing. I'm not sure if the breather or the carb was changed but the breather lid doesn't match the carb mtg post (the hole dia is smaller than the post). The breather looks like most of the ones I've found on-line but I also read that there were many versions depending on the multiple year and engine configurations. Is there a good resource that will help us identify the correct breather housing and the hose diagrams?
