Thanks, but my manifold does not have a mounting "boss", it is there but no bolt holes (guess that is what it is called). Jim Carter states that in 54 (my engine), the horn was mounted to the radiator support. At this point, since I may have to remove the carpet and jute to access the bolts for the stoplight switch and will probably mount the horn where it was originally on the firewall.
