What year did chevy change the Front seat track mounting from 4 bolt to a slip in 2 bolt.
Couldn't tell you when they changed how the seats mount in the monte. If u r good with a wrench you can mount almost any seat u want. If you can weld you can install even more types of seats. Hell I have some Camaro seats that r manual. Why don't like your seats if u don't mind me asking.
