Probably not, although the differences might be in the length of the stalk or the look of the knob.
If you have the two parts in question laying around, take out the one you want to replace and lay them side by side and compare.
I've said for a while that somebody who could develop an interchangeability index that could tell you something like that would make a fortune. Wrecking yards in the US seem to have them--I found that the driver's side outside mirror on my SAAB 9000 was the same as a Volvo part. The yard didn't have the SAAB part, but they had the Volvo part. Maybe you could find a wrecking yard that could help you.
And all the best to you in Cork; I lived in Dublin two years, and one of my great best friends is a Cork man called Finbarr (of course) O'Donovan.
