I have a 99 Seville SLS engine code "Y" is it possible to put a engine code "9" out of a 97 seville. Would it be a drop in or would there be some connections that would have to be changed?
Thanks!

No, your dealing with different body styles. There were some casting changes to accomodate different mountings, and your electrical would have some differences. If you were going 99 to 99, that would be different.
