4x4 front pads are not the same as other 1.2 pads, are in fact the same as 1.3 MJ pads. You should check the disc thickness as well because, from my experience, if the pads are worn out then the discs will be on or below the minimum thickness of 18.2 mm. In addition, the inner surfaces of the discs are likely to corroded to the point where they are not really serviceable.
I sourced pads and discs from this company as I wanted to keep to original Fiat parts with the car still under warranty. http://www.shop4parts.co.uk/index.cfm?action=info.home
I've looked at other internet suppliers offering pattern parts and find the prices comparable.However, I don't know if they will supply in Eire.
Another point, if your front pads are worn then it won't be long before the rears are as well although you should only need pads not discs if this is the first time you've replaced them.
