i am getting a smoking deal on a 96 deville n-star with a blown motor. i am considering buying it and putting in a used n-star in the summer. i can get a good deal on a used n-star from the wrecker because they have a couple right now. my question is can any year north star work in this deville?the wrecker has only 93-95 used n-stars. thanks in advance for the input. i already have a 93 sts ,made me want another n- star for my dad to replace his 89 deville ,4.5.
