Where could I get this rather than online? What stores carry these or can order one?

www.partsamerica.com lists the Weiand (Holley) 7134, http://www.partsamerica.com/ProductD...artnumber=7134. The Offenhauser 5308 is not listed though.

I would call your local Advanced Auto (or whatever the affiliate is called in your area) and ask if they can order it for you. I know from personal experience that not everything listed on the website can be custom ordered from the retail stores.

BTW, what's the big difference in ordering online and ordering from someone local?

Get the 5308 from Summit Racing or Jegs. I highly doubt anyone local will have them unless Summit is local to you.
