Did you take a look at the link Don? the clips were a stock item on all the GM fuel/vacuum lines, the replacements are very close to the originals for once, but way way over priced in my opinion. With a couple of the clips installed on parralell lines the tubes won't slide around so I don't thing wear is a concern, never has been with any fuel/vacuum line I've seen.
I have a selection of blue-spring sheet that I stock for reproducing spring clips for my vintage radio/record player work. I'm going to try and make some of these up, hopefully I won't have to heat treat them. I've done that in the past but it's a hit or miss proposition. You can anneal the material for forming but re-hardening them often leaves them to hard, and they break. I've tried a number of ways of tempering them but I've yet to figure out a consistant way of drawing them back. Might help if I had a heat treat oven.
And yes, the easy way out would simply be to tie-wrap them, which accomplishes the same purpose, but that wouldn't look very original now, would it!
