Milton,
One of the reasons Bill and I want to see the belts first hand. Weather is playing a factor right now. It is a road trip to Sioux Falls, SD from Firth. So once we have some better road/weather conditions we can check it out.
I've done a bit of research on the sizes and found metric size belts that are very close to correct . The metric belts come in two widths , 7mm and 10 mm. The 7mm is really close to 3/8" and 10mm is really close to 1/2". So now it will be down to color of the belts and how the metric belts are marked.
Hopefully we can find a replacement that will fit the bill.
