cletis,
Key word..."Improvise"! When you've got one of these old trucks it's quite obvious that NOS could be found somewhere usually at a high cost or it may not be there at all. People must put their thinking cap on to work out a solution. That to me is "The Challenge", and can lead to positive results which makes a person or group feel "really good" about overcoming that problem. Just like how you went about your repair effort!
Its also fantastic that today we have a place to go such as this Stovebolt website to look for solutions from others. Many heads are better than one!!
Now I just have to figure out how to repair my Defroster Blower Motor!
