Ok here's what I found out.
my stock brake line is 13 1/2 inches.
Stock Yj is 16 1/4. 18.99 at Orileys
Oriley's sells a extended xj line (18 inches) for 16.99
They also have an extended YJ line (22 inches) for 18.99.

I'm leaning towards the 18 inch line. Is 5 inches added
length too Long for a 3 inch lift?
