I have a 58 chevy 3200 that has fenders from a 59 on it. I have the fender emblems for a 58 I want to install but I'm not exactly sure where on the fender they go. I can see from pictures of other trucks roughly where to put them but was wondering if there was some measurements others have gone by like "x" inches back from the fenders edge or something like that. I'd like to drill holes just once....any help much appreciated!
