Missing "Lift-the-Dot" Connector

[Michael.Lytton@sierra.com]

     Hello:
     
     My 1970 MGB doesn't have the lift-the-dot connector on the top center 
     dash like I remember seeing on my '72 MGB years ago.  This connector 
     is used for the full tonneau, and should be below the rear view 
     mirror, if I recall correctly.  I mean, there's not even a hole on the 
     1970!
     
     I would like to buy a full tonneau and fit it, but do I have to remove 
     the windshield and drill a hole for that connector?  Has anyone else 
     had to deal with this?  Seems like a lot* of work for a tonneau...
     
     Thanks in advance!
