I was just curious about the differences in the horn pads for the 70-78 models, because I can't freakin' remember - ! I'm posting this here so that others can learn as well - part of the Z history. Here's 2 pix I have of horn pads. Can someone tell me which years they're for? And, anyone who has different pix of horn pads for these particular models is more than welcome to post them here, so that others can be educated on it as well. Thanks!
