Most body parts should interchange, mounting-wise.
The '03 has different accents for the font cowling (fairing) compared to the '02 and earlier which look similar.
I think the accents for the lower fairings may be slightly different as well as I've heard they changed the size of the lettering and placement.
Physically, they should work.
The lower inner-cowling is different on the SP1's and SP2's due to oil cooler placement.
The SP1's had the oil cooler mount horizontally and the SP2's are mounted vertically and to the left side. The SP2 lower cowling has the opening and screen for oil cooler ventilation.
