Brake Upgrade Question
 

I'm installing a '93 Cobra Rear in my '89GT. FRPP tech line recomends I upgrade my booster, master cylinder and proportioning valve to the '93 Cobra ones. What about brake lines? Were they the same? I'm talking about the steel lines. I'll call my dealer tomorrow to see if I could order '93 Cobra lines but was wondering if any of you knew??
