Brake line question on a mustang

I'm working on a 79 fox body mustang and the rear brake like is leaking from inside the interior.... my question has anyone changed the front to rear line on a early fox body?? do i have to pull out the seats?

i would just run a new line under the car

Does the line run threw the interior from the factory?

The line runs along the passenger side under the carpet. You have to remove the rear seat to get at where it exits the passenger compartment.

OK , Thanks... Next weeks project!!! just wanted to know for sure that i had to pull the seat and so on....

I know that the later fox bodies (87-up) have the rear brake line running along the passenger side frame rail under the car, they must have found out the hard way that running it through the car was a bad idea!
