Got the front wheel done. The die size used on the spokes is a #2 - 56 TPI. There is probably a metric equivalent used now, but the 2-56 works well on most all the 105 ga. spokes I've ever found. I have a die that works on the .120 ga. spokes also, all I can find marked on it is .133".
Don't like too much and it will be done. Kmart had these tires for $8.50 each. They are 26 X 2.125" Ching Shins and they look similar to the original Uniroyal Nobby's. Thanks!!!
