"McMaster-Carr" has 1" High strength neoprene rubber balls which will work in our Spicer U-Joints. I think they are about $8.00 or so for a package of 5. Pretty cheap. I have had great luck with these people finding hard to get high quality products easily used in restoration work. Most importantly, they are great to deal with.
