I just bought a 67 Camaro 12 bolt that has a QL code on it. Iknow it's for a 67 because it has a 67 casting date and it has the extra bracket on the passenger side. It is a posi., it has 4:11 gears aftermarket gears on a three series carrier with a ring gear spacer. I bought this for $500.00 . I know I got a good deal but I would really like to know what it came with from the factory. I've looked in a book I have but it didn't list any Q codes for 67 or any gear ratios higher than 3:73. 68-69 do have Q codes but nothing with an L and they are 4:11-4:88. Any help anyone can provide will be great. I also got a 12 bolt from a 70 Nova with leaf springs and slapper bars with 3:31 gears for $200.00 with this deal.
