Technical 32 wishbone ball cap

I am missing the steel radius rod ball cap on my 32 K member. Can someone tell me if other years use the same steel ball cap? Any help is greatly appreciated.

 

My 34 has a model a rubber ball

 

Oops, I misread your post I have mix matched the steel caps too but don't remember if I modified the flange on it. I know that post 1940 caps accept the larger diameter ball though.

 

Thanks skidmarks!

 

There is one for sale over on the Ford barn classifieds.

 

Saw a couple post 40 year caps but no 32 to 40's there.
