Dash Clocks

Hi,
My Freebie's clock display is knackered. It is a XQH100100, but I was wondering whether I can change this for one of the other very similar looking 8-pin Rover clocks like the XQH100010 or the XQH100102, both widely available on Ebay?
I do not need radio connection if that makes any difference?
Cheers
Tempo

The Rover clock is fully compatible, however it has a red display rather than green.
