I have an dual carb. Offy intake on my 48 Dodge flat motor, and would like to put the stock style oil-bath air cleaners on. My question to you is, which make/model vehicles would have a unit that was no more than 7-1/2" diameter? The smallest I've found so far is 8-1/2". This because the carbs. are that distance apart. I am running the stock B&B (Carter) carbs. Need this info so I can start hunting them down. Thank you!
