I Have been toying wiht the idea of swapping out the rear axle in my American. One axle tube is slightly twisted/turned in it and I have another good 3:31 axle. The reason I haven't doen so is the spare does not have twingrip and the one in the car now does and it still seems to work. So, I just don't want to tear apart the car to swap out the twingrip. I see on Summitt that there is a detroit E-Z locker for the Dana 30. I wonder will it fit in a 1969 AMC 15 open carrier? The price is good at $259. I wonder?
