The Studebaker pads are a great match for the thickness and design. But be careful that the bolt on them you use to bolt them thru the fender and the brace is big enough and long enough.
I searched for a long time to find either white or black rollers for my Tee Nee. No one I could find makes one long enough with an integral shaft that you can cut down. I'm surprised you found some up there Bill. If there was any way you could track down the manufacteurer it would be a big help for others in the future.
I finally bought two rollers (no integral shaft) from etrailer that were long enough to make both pieces for each side. Problem was it had bores to fit loose over a 3/4 shaft.
I found some 7/8 stainless round bar and machined the exposed shaft area to 5/8 and the areas in the rollers to .800 in. and pressed the cut down rollers on to the shaft.
I wet sanded them on the lathe and used ArmorAll vinyl spray to shine them up a bit.
It was a lot of work, but I'm always looking for an excuse to work with my lathe. They turned out nice and the shafts will never rust.
Sure would be easier if we could find the same ones you found in Canada.
