Dear Milton, Walt, Tom, Dan, Dan, and mid-60s
"its gotta be narrow white walls" types,
I feel your pain brother! White walls of any sort are getting increasingly hard to come by and narrow white walls are specially endangered. If you can't find anything that fits your performance and appearance objectives, you might consider Diamond Back tires:
http://www.dbtires.com/They are expensive, but they remanufacture brand name tires to give you the appearance you want. Basically it appears they can make any side wall appearance that you desire. I have been drooling over some BF Goodrich radial T/As remanufactured with nice 1" white-walls for my trusty wagon. She has had white-walls since about 1979 or so, I can't let her down now!
Hope this helps!
Cheers, Edouard
