My replacement "kit" for my 62 long w/b fleetside was a joke. It had a few lines close and they could be used but one was not close to fitting.
I debated with my self if I should just make my own and thought the "kit" would be easy. Never again. and I have had for years the flair tool
and a few benders.
Now there is a new alloy of tubing that is easy to bend and will not rust like the steel ones did. And not hard like the stainless.
The poor fit was from about four years back and hopefully today they are near perfect. But now I just do it the way I was taught and just bend my own.
Sorry I do not remember what the new tubing is called but in my mind that is the way to go.
I converted the 66 Imp. to a dual system and the new stuff is a breeze to work with. You can form it with your hands and not kink or collapse it.
If everything is new and dry you might want to use DOT 5 fluid. It is not hydroscopic and will not damage paint. Do not mix it with DOT 3 or 4.
Good luck. Howie
