WTB - Standard Wheel Horn Button and Trim

I bought a very nice used horn ring and cap with the "fratzog" logo cap like you have pictured . I planned on buying a blue reproduction wheel and putting it on my 70 dart as well! I haven't gotten around to it yet. I believe that my horn ring was from a '68 coronet. I'll be pa ting close attention to this thread.

I also just noticed that my horn ring has pieces of chrome that extend towards the column in between the spokes. So it looks like it wouldn't fit on the 1970 style wheel due to it have a larger diameter hub. Is there any difference in the materials or grain/pattern from the 67-69 style and the 70 style?
