Upgrade to 2004 Zip Tube and Air Filter Box

I found an air cleaner/intake assembly off a CVPI on ebay and decided to grab it since I've been wanting to do this upgrade for awhile. It includes the Marauder-style air filter box, 80mm MAF sensor and straight zip tube. I don't want to bother with re-programming the EEC/PCM (broke :frown:) in order to use the 80mm MAF sensor. Is there any way I can do my own modification from the stock 70mm MAF sensor to the zip tube, or will I have to buy an adapter? And if I do have to get one, where is a reputable place I can get one (and cheap)? Are they available at any old auto parts store?

Thanks.
