If you want the best in Battery cables, these are probably as good as it gets,
I put them on my 65. the price is up from a couple of years ago, but I think they are still worth it. The spring type clamps are by far still the best imop.
Have seen some guys use a 75 to 79 Nova overflow tank in the fender behind the battery. Take out the battery and it fits in there quite neat. I think that is what I am going to do on my 68 Beaumont 2-door post.
