I have done it (twice) but it has been awhile, so from what I remember...

I bent my own replacements. You need to find a supply store that carries 5/16" steel lines. The originals are 8mm but they interchange in this application.

Once the lines have rusted enough that they need replaced the fittings at the transmission will be rusted to the lines. Cut the lines at the fittings. You will need to reuse the fittings at the transmission and the radiator. You may have to drill out the fittings that were rusted solid to the lines at the transmission.

I checked my maintenance records and it took one 12" and 2 60" pieces of 5/16" line. You will need a fitting to connect one of the 60" to the 12" tube. They will already have male fitting on the ends. The 12" piece should be closer to the transmission rather than near the radiator.

Once you have the old lines off you can bend the new lines to the same configuration (more or less). Bending the tubing is a bit tricky. You will need a tool similar to this one shown on Northern Tool's site:

It is very easy to collapse the tubing as you try to bend it. Especially so with the bends that approach 90 degrees. It might be best to clamp the tool in a vice. With the tool in a vice you can concentrate on keeping the tubing tight against the tool with one hand while you apply the force to bend it with the other hand. If the tubing is allowed to come away from the radius of the tool the tubing will collapse.

Cut the supplied fittings off of the ends of your newly bent lines. Replace them with the fittings off of your old lines and flair the ends. Match up the new flare with the flare size at the radiator fittings.

I was always able to just leave the 90 degree fittings in place at the transmission. You suggested yours were rusted and leaking. Perhaps you will find that it is the line that is leaking in the area rather than the fitting on the transmission.

I would attach the lines at the transmission first and then the ones at the radiator. You will probably need to do some final flexing/bending of the entire length of the lines to get a good alignment with the fittings on the radiator.
