Today I picked up a Volvo Sunglasses holder from my local dealer
http://accessories.volvocars.com/en-ph/V60/Accessories/Document/VCC-472708/2012/D5/Manual/R.H.D
I went for charcoal as it is an excellent match to the current grab handle.
Here is a picture of the holder side by side with the handle I have removed
Now we need to cut off the lugs carefully with a sharp craft knife
Then I knocked out the little metal top hat sleeves that were in the Volvo holes (they didn't need much force to remove them).
Then I made a couple of top hat bushes to insert into the holes.
The pressed metal sleeves can now be thrown away (shown at the bottom of the picture above).
Then I offered up the holder to the roof and fastened one screw loosely into position
Then, with a little bit of twisting, you should be able to screw the final screw into position. Torque up correctly and close the screw cover caps until they click shut.
Voilà ....
