Rearend gears in 85 2.8
Yesterday I typed my RPO codes into the rpo decoder on the main page and one of my codes showed me as having a 3.42 rearend. Is there any idea how many 85 sport coupes were produced with these gears and had the 2.8 engine?

I think every 85 2.8, AT camaro had the 3.42 gears. Manuals might have received a different ratio but I think posi was only an option on Z-28 and Iroc
