Mark,, the switches should be fairly easy,, just undo the knots and they should push back, As a safet measure,, just in case,, I'd tied a string to each one so if it falls behind you've got string attached to fish them back out. Highly unlikely but better safe then sorry. As well, if you do keep your eyebrow panel,, Sem color coat probably has the color to match your exixting panels,,
