yes, a 67-69 Camaro rear axle will bolt right in, also a 68-77 GM X-Body car ( Nova , Apollo, ect ) the X-Body from 72 -77 will have the 8.5" rear axle, which is almost as strong as a 12 bolt and a lot cheaper to buy and can still be found in wrecking yards. If you go the 8.5" route, you will have to shorten the drive shaft one inch.
