For those that want a little more "authenticity" in your engine compartment, look here -

Packard wire, 7mm, just like the 50's, 60's, but it's modern suppression core wire, not solid copper. Unfortunately the word..."suppression" is kinda large, but so is the word..."Packard". Maybe...the word can be scrapped off..!??
There's another plug wire on future pages also.
A lot of other interesting stuff too.
