Quoted from spfxted:Thanks Dude! So, all I need to do is pry that nail forward and pull it out. I already have other rails, so I'm not worried about these.
Pull old rails off after removing nails. Put new ones on and put nails back...or screws, etc. Got it!
Fairly straight forward just take your time. There is one screw and nut at the front of rail near the lock bar to remove both sides. if your not set on keeping and reusing the old rails you can simply and Slowly pull them up and at an angle. Note that it is best to do one side at a time and you Really should lower the backbox mount arm so you can access the full length. Just remove the 2 screws holding it to the back box and let it hang. Heat can help to slightly soften the old tape as some can be a Bear! Just be careful not to overheat the decals! Pull upward and out only so as not to tear the cabinet art. Use a sharp straight blade razor to remove excess black adhesive tape so the new rails mount flush. Finally, I strongly recommend the 3M moulding tape (link below). Pretty much the same as the original used. Don't use cheap foam tape! Good luck and take your time!
