KQ rear with 4.56 gears

[Keith Tedford]

Our L78 car has the KK 4.10 rearend while the COPO has the KQ. Until people got into restoring these cars, very few knew the difference or even realized that there were two different rearends. The drag race crowd would be the first to realize that there was a difference. My feeling is that anything but 4.10 gears in a KQ rearend would have been swapped in at some point in the past. Could be wrong though. This is what makes this hobby interesting.

I thought 4.10 was the lowest gear as factory installed on 69 COPO Cars and if you ordered 4.56s the parts came with the car for dealer installation. It was noted on the Window Sticker and POP with the "right" code, but not the rear axle tube.

My 69 L78 Nova was ordered with (possibly copo'd from what people have told me) and still has it's original BW coded 4:56 12 bolt, car is an April 69 build

Ummm... me too

I've got a KQ rear that's dated 02 25 which is far too early for my Chevells's 07D build date. I'm prepared to swap or sell my KQ once I can find a better dated KQ rearend for my car. Anyone got a late 69 KQ rearend to sell or trade?
