ROchester Single barrel Air cleaner

Need a little help finding the air cleaner for my rochester single barrels. I like the set ups on Vintage speed. But not sure that they will work. My air cleaners need to be 2.5" any thought would be great. I like the simple finned air cleaners. Everything on Vintage speed is 2 5/8 thinking those might be to small a base flange..

Thanks

 

You can buy an aircleaner adapter from nightprowlers:

Or make your own out of exhaust pipe reducer like I did:
