BLUE, Is this the post you found?
My 16 inch rims. They had them in stock years ago at TireRama in Missoula. I went back to enquire about them and they said they could order them. I think any good tire shop could get them.
I hope they still work after I replace my tie rod ends!
Eureka is in nice country! I bought my '48 from a guy in Heron in 1992.
