I just discovered my '69 has a 3.07 limited slip installed instead of the HA 3.73 gears. It is good as it keeps the RPM's down on the new 396BB that is in there. Makes for a great cruiser where I am only pulling 2600RPM at 70mph, but terrible at lower RPM performance. When I bought the truck, the PO and my own research showed that the truck had the 3.73 installed, but neither of us actually opened up the rear end to count the teeth.
