You're on the right track - lots of penetrating oil needed for the brake
line to bomb junction - use a TUBING wrench to remove this - 7/16", but not
a standard open end wrench - a tubing wrench looks like a box (closed)
wrench, but with just enough of an opening in it to pass the brake line. Be
careful here since you don't want to damage the brake line if possible - no
splices allowed - get a "universal" brake line at auto parts store and
carefully bend to fit . . .

If you break the banjo bolt, get another - they might cost zero at a parts
yard (you pull it) - of course you DID get a spare before you broke the
other one? ;-)

Yours is a late model and should have the rubber o-ring seals - they won't
be damaged if the banjo bolt breaks, but you really should change the
o-rings anyway.

The hardest part about this job is the "limited" access to what you need to
get at. Other than that, it isn't an especially nasty task.
