The Euro MK1 Focus ran from 98-05, and the MK2 crossed over in '05 too. I guess they made both models that year like when they made the new '04 F150 along with the old one and called it the "heritage edition". Look for the EDM 98-04 / '05 MK1 bumpers, the MK2 is a larger wider car and they have nothing in common with the American Focus.
You can only use 98-04 European Focus sedan rear or all front. The 2nd gen is a lot bigger than your 1.5 gen. Either way, to convert a half-gen will take a lot of parts. The rear - you need trunklid, taillights. the front - hood, fenders, radiator support, washer bottle. Your best bet would be to find a SAP rear and front to match, it would be a lot cheaper and easier to find. Yes I know how rare and expensive the SAP is...
