ok ive seen some 1st half year cavs(03 before the change when they had the 00-02 look) have the ecotec in them. my question is i need to take my 2.4l out it went bad and have a sweet deal on a ecotec/trans can they be swapped given they came in the previous stated . if so whats involved with it. i have the trans and engine of the ecotec(03 model year) to replace the 2.4l engine/trans. did the mount change stuff like that?
