Before I drill any holes in my dash I thought I would see if people recommend upgrading any of these switches, in which I am worried if the hole diameter will change. Basically I have the "Lucas style" toggle switches that came with the complete kit and the wiper kit, the horn button, the light switch, and ignition. I'm mostly concerned about the Lucas style switches. They seem kind of cheap and that small bezel/nut on the front doesn't look very aesthetically pleasing and worried it may not be wide enough to hold firmly on the dash. I like the vintage look, however. Is this concern warranted or are they good enough? If I should replace, any recommendations?
