jumper tube ???

Interesting jumper tube? I had a 69 Dart once that had a flex hose that went to a very small steel line that went to the wheel cyl is that the tube your talking about.Mine was bent like an s shape.
I beleive you hit the nail on the head here for him the u-clips are standardthe line you will have to make. You will have to find the bracket that the hose attaches to at the wheel , Now other then on here I wouldn't know where to look for the bracket, Although I might have a set on a 70 340 front clip out back all other drum brake set ups I threw out. I'll see if I can get a picture I have alot of pictures to take and some parts hunting for others after I do some bill paying today. Steve
