I have a Dana 35 with ABS on a 1999 4WD with 4.0

Im trying to change the rear brakes so I bought new shoes, drums, wheel cylinders, and both hardware kits.

I decided to to the right rear 1st and it all came apart ok except when I went to remove the brake line from the wheel cylinder I broke the end of the line off.
I think the brakeline is the 3/16 one but Im not really sure also I have no clue how long it is. 72' 51' 20' 30' 40' seem to be my choices for length.

The line I broke is the one that goes from the RR wheel across the axle.
