Difference between models 730/736

[wayneashford]

I am trying to get an ABS sensor sorted for my ph2 172, the local motor factors is asking whether it is a F4R 730 or 736 model - I do not know the difference.
Can anyone help?
Search tells me it might be the difference between 172 and 182 or ph1 and ph2 but can't seem to find a definitive answer - I would like to think the motor factors software can tell the difference between a 2002 ph2 and a 2004 182 (if there is indeed a difference between ABS sensors).

Engine codes so it shouldn't have anything to do with ABS afaik, one of the traders would be best places to say.

i'm wondering if they can't tell the difference between ph1 and ph2, whether there was a change but the intermoto part is from 2002 on which mine would be - i'm guessing that would be a 736.
