Last week I posted re: horn problem. I put the shims in and did the fix as recommended. Works just fine and it was real easy. However, I do not know how much longer I can get out of the pin. It looks pretty worn. Anyway, I will probably want to replace it and the whole ring. How difficult is it to obtain this part. A friend told me that he was looking for the part and that it was listed as "out of stock." Where is the best place to order. Again, thanks.
