I'm 34 years old and some of my friends are in their 50's. To all you young guys, that happens as you get older. Age gaps get very very small. Anyway, when I talk about my stang, they always bring up stories about their heydays. Especially, the 4.11 posi rear. These days you only hear about 4.10's. Where did the 4.11's go? Was that a mopar thing?

Well back then you was installing gears in 9' rear ends that accepts 4.11.Ours are 8.8's that take the 4.10 ratio.
The 8' rear end also could take the 4.11 ratio gear.So yeah there still around.
