I bought a high output alt. from ebay. It was listed to fit my 89 Formula, but alas, it doesn't. The guy will take it back, but i got a good deal on it and i want my car back on the road!!

How hard is it to swap the front housings? I have taken the 3 bolts out, but i havn't taken the pulley off yet. I figure once the pulley is off then the case should just split apart easily. How hard is it to take the bearing out? I don't want to reuse the old one.. the rear one was the problem... its missing 3 *****.
