68 12 bolt

Did the 68 camaro come with a 12 bolt rear end?
If not which rear end will fit my 68 camaro?

All Z/28's and some SS's came with a 12-bolt.

67-69 Camaro 12 bolt and 70 Nova 12 bolt are direct interchange, except for the multi/single leaf issue and non-staggered shock configuration on the 67's.

From CRG:

Q: What models received 12-bolt axles?

A: 12-bolt axles were installed on all SS-396s, all SS-350s (with possible exceptions in 1969 noted below), and all Z-28s. In addition, 12-bolt axles were installed on the following cars:

1967-8 L30/M20 cars from approximately Dec 1966 through the end of the 1968 model year.
All models with the 1969 factory 4-wheel disc brake JL8 option.
1969 cars with the LM1 engine. It appears that the 12 bolt was used with all 4-speed and automatic transmissions. Use on the manual 3-speed transmission cars is unknown.
1969 cars with the L65 engine (which replaced the LM1 engine) and 4 speed transmission. Data is erratic on this drivetrain combination, some cars have 10 bolts, some have 12 bolts. Please contact us if you have a car with this drivetrain.
Note: GM documentation indicates that 1969 SS-350s and LM1s with automatic transmissions may have received a 10-bolt rear axle. So far only SS-350 cars with powerglides have been observed with 10 bolt axles. Please contact us if you have a car with this drivetrain.

Furthermore, mid-year 67 models with 12-bolts received a passenger side traction bar or "radius rod" which was not used after moving to a "staggered" rear shock set-up in 1968.
