"maintain the original dimensions."  

Yes, assuming the original dimensions were optimal.

    Ken, I beg to differ.  It is vital to keep the overall height of the key and keytop the same AFTER the new tops are installed as they were BEFORE.   If one is removing the original thin ivory and replacing with thick plastic, the key will be substanstially higher when put back into the piano.  This can lead to the keys contacting the fallboard, keeping them from returning to their full up position, causing the tops of the sharps to be level with the naturals when depressed, and/or a myriad of regulation problems.  The first rule of keytop replacement is "maintain the original dimensions."  If you are replacing old with new of the same thickness, fine.  If not, there may be a problem.  FWIW......

  Take your time, Mickey. Never take any wood off a key.
