Inline Tube

Looking at getting preformed brake lines (front to back) for my ‘67 Barracuda and I was looking at their ads...then I saw a lot of bad reviews. Anyone here have experience with them?
My experience was not good. This one item in my disc conversion cost me 6 weeks. Wrong parts in the box, and asymmetrical flare was a nightmare.
My recommendation would be to check Dr Diff, or make your own lines.
