I have a 77 Aspen R/T. when i bought it the car was all original, and well i have gone with repairs of drivetrain up so i can drive it and have fun while building it up. The rear end is currently about to blow. It's an 8 1/4 with original 3.23 non posi in it. I for awhile was just gonna find an 8 3/4 to put in but would have cost me more so i'm heading a different rought. sticking with the 8 1/4 and heading for 3.55 gears. i was gonna go for 3.90s but i enjoy to drive the car as much as i can and gas prices and the rpms would just kill me. My question really is on the posi unit. Would you prefer a Auburn posi or TrueTrac locker. What would be the real difference. If you have a car with some power and probably every month you wanna have some fun and take it to the track while driving it as a daily driver which would you choose?
