I have to put closure to my tire episode.
I found 3.50 x 16 Cheng Shin model C-155 tires fit. I bought two rear tires and mounted them myself. They fit close but do nut rub. These tires are built along classic lines. I got them at close out prices, new for $6.59ea. Basically $23.00 a pair off of ebay. I went back to buy a second set and they were gone.
Here is how they look on the bike. The bike will be finished within a few days.
