Imperial Heaven in Nebraska would be an easy day drive from Denver. I'm not sure of their location, but it is mentioned on the Imperial web site. As for tire sizes, I found Coker Tires online to be very helpful. They even have a conversion table for bias ply to radial sizes. I didn't buy my tires from Coker, but if I ever hit the lottery jackpot I might consider the 2 1/2 inch whitewall radials they have, which sell for $160.00 each! Hope everyone enjoys my new font, which I believe is default for most E-mail. The other was too big and clumsy looking. Bill '59 Crown
