old fuel lines and brake lines -Replacement Where and How? Tech tips please!

Like you I looked for pre bent F body lines, found zero. I did read on a forum that Inline Tube makes just the front line for the F body, but they can be 2 styles. I found nothing on their sire, so I would just call them and ask.
I have not started the task, but I had many people brag on that nickel/copper lines, so I ordered a roll and the armour for it too.
