There is a very good chance that this part is the same for both models, since the I am lead to believe the timing gear is.
Yes, It 'Appears' that they are the same part, although I have heard tell they are 'Matched' -ie- the IP timing-gear and the oil-pump gear...
Best replace them as a 'Pair' anyway. IF you must change from one type to another, Its important to use the correct bush-holder for the Oil-Pump gear. (The part that fits into the block above the oil-pump gear) One is slightly shorter than the other, and the bushes are different. Just replace all three parts from the 'donor' engine would be best....
I believe the Bush directly behind the timing-sprocket/IP Timer is the same on all models, and does wear, which is easy to spot. With shaft installed, and without the IP Timer fitted- Pull/push it horizontally, There should be just perceptable play, and the bush should not be loose in the block....
