Howdy, ran across this old entry after digging thru my meager speed equipment to see what I had to build a car for the H.A.M.B. Drags next year. Found my Sun tach, warranty card says April 1963, Carl's Muffler Kansas City, Missouri. Try not to be stupid, but I was ignorant of this Speed Shop in my hometown, and just down the street from where I work to boot. Ronnie's and Arrow Speed were the ones to go to, in my era. Google also pulled up the Bill Thomas obituary from 2015, my condolence on your loss.
