Simply cut off the old fitting as close to the end as possible, slip on the new one, then flare the line. The line will be a little shorter but that's usually ok.

Yes, I'm not describing the entire process. YouTube could walk you through it as it did for me. I've used this flaring skill a bunch in recent years due to stuck fittings (on Volvo) and rusted lines (on Mercedes).
I have to admit it would be pretty empowering to just fix the line and not have to worry!

Out of curiosity do you remember the size of the fittings etc I need?

After I posted this thread I did attend Youtube University and the process looks fairly straightforward, however things never go as planned for me regarding car repair.

I make the drive about once a month, sometimes more, as I work out of CLT airport. Yeah, about 3 hours.

The rear caliper fittings are M10 x 1 bubble flare. However, before you try to remove yours, know that the caliper fitting holes will have closed up due to rust, grabbing the fittings, making them hard to remove. Before you can install a new fitting, the holes need to be bored out to the correct size with an M10 x 1 tap. I have not yet done this but need to on some calipers.

If your rear calipers are working but their fittings are stuck, you're best off leaving them in place. Examine the boots for breaks and the pistons for proper movement with the calipers on the car. I started a draft thread about caliper failure but haven't filled in that info yet.

Also, couldn't you just replace with something like this?

Why the need to flare/make a new lineset?
These are replacements for the RUBBER hoses, not the hardlines.

Sometimes it's easier to replace a fitting and re-flare an existing line. Sometimes it's easier to just replace the whole hardline.

As abscate mentioned, the NiCopp hardlines are great. They can easily be formed and flared, and they don't rust. I've used NiCopp stuff for lines on my F150, my Thunderbird, my LTS, my 850, and my wife's 76 Beetle.

I had to bend a really wacky line for my old Mercedes. With NiCopp, it was a little tricky to make the bends without flattining the line. My line bender tool had too large a radius for what I needed so I tried bending it over a pipe. What methods do you use to get good bends on NiCopp?

Bend it around a socket of the same radius as the curve needed. It’s a bit of art here

Use big sockets and gently work it around the radius. Don't do the whole curve at once.
