Just for fun I looked up 68 Camaro specs at the GM website. If the car came with a 230 or 250 and a Powerglide, std axle ratio was 2.73 unless the car was a Rally Sport then it was a 3.08. A 3.55 ratio could be had as a performance option and 2.56 as an economy option. Of course enough time has passed that there could be anything in that axle housing! To get different gears cost less than $3 on the window sticker!!! Jay 6155
