Hey can anyone help me here, I know it's not an El Camino I own a 64 Malibu/SS that I am wanting to use the original AM Radio. My problem is that the knobs slide off way to easy, the guy I bought the car from had an aftermarket radio. The shafts were bigger than stock, how can I fix this without wrecking the original knobs. Thanks for all the help and advice. :dontknow:
