Amazon.com has gotten pretty big in to Raybestos parts. On this particular part they are a buck cheaper and with $35 you get free shipping. Raybestos is my brand of choice for old vehicles. Some of it is US and some of it is Chinese, but the quality looks as good as what we bought over 50 years ago.

NOS shoes hit eBay quite often. They are probably asbestos, but I used asbestos pads from the 50's until non asbestos came out. If your shoes are rusty or need to be recoined, you might look at NOS shoes and have new pads put on them if you are afraid of asbestos.
