Wanted Centre Console for Early Alfetta GT

[marks alfetta]

Hi

I'm looking for the section of the Centre Console which holds the radio in an early 1975 Alfetta GT.  My centre console comes in three bits of which I have two of the bits.  I've got the bit that sits around the gear lever and the part that sits in front of the heater/ventalation unit.  Want I don't have is the part which screws to the section which sits in front of the heater/ventalation unit and holds the radio. 

Mine is the early type and a bit unusual so I've attached a couple of photos.
