waldo53: the Smitty's I purchased came from a place in Florida I think it was called the Hot Rod Shop. Drop me an e-mail with Smitty in the subject line and in the meantime I will dig out the boxes. For those considering cost I "thought" I would try the Flowmasters. The shop here had two different ones. One cost $60 and the other was $80. The price was installed. I always loved the Smitty and when I say the advertiser in Old Cars Weekly I purchased two of them for $60. Shipping was very little to my address. I'm getting to be an old fart but remember these quite well. The correct spelling is Smitty!
