Pm "RGWM", Italiautoparts or autolusso - I'm sure they will be able to help you out.
There are two different styles of rear pads which changed around the time of your car but I'm sure the guys aboe will confirm whether the calipers themselves are interchangeable
if it takes the spring type pads then YES it'll work. if not it won't. in fact both types will fit & work on either year but you'd end up with a mixture of pads. Been a 2.o litre most likely yours will have the 'slip-in' [ with tabs on the edges ] type so the '98 won't suit your pads.
