67 Barracuda front frame rail

My 67 Cuda has a bad left ( drivers side ) frame rail . I will replace it , already have n o s
piece but they are available from Classic industries and check out (A B S)
Auto Body Specialties . Don't play games with the frame rail if it has several areas that are rusted away . I have patched some in the past , I cut back to good metal and butt welded new metal in . If you are bumping up the horse power considerably I recommend cutting the floor pan over the frame rails on right and left side then box them in as well as frame connectors . Good luck with your project
