Steering wheel options for us Early A drivers

I am using a smaller grant wheel on my 66.

I wanted to go with the 3 spoke like toolman has on his but I havent been able to find the horn button and center cap for the wheel I bought. And when I do see them on ebay they are usually well over the $100 just for those cap and button.
i think this wheel is 14". Ive only had it out one time but it didnt seem to turn that hard and it is manual steering.
Sbould anyone know of a cap and button let me know. Doesnt matter if its the plymouth either!
Thanks Rod
