I have a "Horn Wire terminal Support & Wire" (NOS) part #B8A-14308-A. It was recommended & obtained as part of a 57 to 58 steering box conversion which I've posted about on this site before. So I'll not repeat it all again. Suffice to say the conversion as far as the horn is concerned, went off the rails! My question is, does anyone have a parts or interchange manual that will tell what the part is supposed to do or fit? I thought that it was possibly a replacement for a worn 1958 horn contact ring. I have here what is supposed to be a 1958 horn contact ring & turn signal assembly, (also a 59 Edsel one that appears identical) but it does not appear to fit them. What does it do or fit? Any help appreciated. Thanks

Paul
