O.K., I just crawled out from under there...

You didn't break A rear brake line (they are located on the rear side of the axle, away from the shocks). You broke THE rear brake line. If it broke near the top shock mount, you are seriously lucky that you didn't take out one of the 3 fuel lines in the same area (actually mounted right next to that brake line).

You can take it in and get it spliced for a few bucks. A good brake shop will be able to fit you for a hardline and compression fittings for less than $75 Alaska dollars.

You are 100% correct, to remove that entire line and replace it (with one from another VX or a SWB/2dr Trooper) would be a PITA. It is one piece all the way to the ABS module. Also, I've found that the plastic clips that hold those hardlines to the frame tend to harden and get brittle. Trying to pop out a line will break it, and then you'll be left with a floppy brake line. You'd need to get all new clips as well as a new line.

I would still stick with a hardline repair unless the break is on or very near a bend.
