Uhh, there's a change around mid '99, if I remember that right... ... The bolt pattern changed on the block. You'll have to look at your frame and see if they are the same, and then check the side of the engine and make sure it has the same bolts as the 24v. Most of the 12v have both set of bolt holes... .
