Same-same.......there's a chance the Monte rear has an 8.5" ring gear. So, besides the gear ratio change, you could be getting a stronger rear end. I believe some of the later 1st gen Monte's got an 8.5" 10 bolt.

should bolt right in

If the monte rear is 8.5 and your original 8.2 then the driveshaft will need to be shortened 1". The 8.5 has a 1" longer snout than the 8.2 and the 12 bolt, I just did the swap myself and had to modify the driveshaft. other than that they bolt right in.
