snip " From: "Mark Price" <mprice@xxxxxxxxxx> " " I see on Summit that there is a detroit E-Z locker for the Dana 30. " I wonder will it fit in a 1969 AMC 15 open carrier? From: sandwichmaker d30, dunno. i'd tend to doubt it. d35, yes. snip Just wondering on this.............. A locker acts differently than a Twin Grip, correct? The locker is not as "streetable" as the Twin Grip? Doesn't the locker sort-of ratchet instead of smoothly transfer power? The locker is more noisy than a twin grip? I've never had a locker or seen one but I am under the assumption that they are intended for off road use, and I don't really know that for sure. Can anyone help answer these questions? Thanks, Armand
