I have bent lines and fought to make them work and then i have done it the easy way. Use braided stainless with AN connections. Measure carefully and route them neatly you will be once and done. Just my experience.
Just get some for a turbo 350.They should be 5\16 tubing.Some 700's use 3\8 tube and some have 5|16 tube.If your trans fittings are of the 3\8 just swap to the 5\16 style then very little effort is needed to tweak them at the trans end.Thats how I did my 78 using original th350 lines
