1969 Rear
My car is a '69 base 400, w/Turbo 400. As it is factory A/C, it should have 3.23 posi. The rpm at freeway speeds lead me to believe the ratio is not 3.23, and I wonder if this rear end is actually a 8.5 due to the ears on the bottom edge.
The tag references "limited slip" lubricant only. I guess I can pull the cover and measure the ring gear diameter and tooth count, but does this look like a factory 8.2?
