I ordered up the Classic Tube set for my '67. First off - the stainless is not very forgiving. The pre-bent lines are good, but not perfect. Whereas steel or NiCopp will give a little to get that last move into the fitting, the stainless feels like you are nearing that "kink it" point much sooner. The long line is a real pain. It comes folded over once in the box so you have to try to figure out the proper un-bending to make it correct. I'm using a lift and it's still a pain threading the line through the X-frame and getting it oriented right. Might be easier on a frame-off. If I was going to do it again, I'd do NiCopp. Perhaps Classic Tube will offer pre-bent NiCopp someday.
