I have a rear line that has rusted through. The ends are both bubble flare ends. Does anyone know the diameter of the line? Is this 3/6" , 1/4" or metric for this year? If metric is if 4, 6.5 etc??

Has anyone replaced these? I have read that on other sites rusted lines is common on this car and from the looks of it, I need to replace all 4 lines as they are just about all shot.

Would the ployarmor tubing be best? Can I buy a bubble flare tool to flare polyarmor? Does someone sell the lines already bent to fit this year? Should I be looking at a different type of tubing. The typical stores I have near me are Autozone, Pep Boys but when I was last there for our 94 Tbird, no one carries brake line for with a bubble flare end. Are the connectors metric on the 97 Merc Grand Marquis?

Any other advice would be greatly appreciated.

Thanks
