Anybody have any info on 67 camaro axle codes. I have several books but can't find this particular code. It's a 67 camaro 12 bolt cast number 3894860, cast date F 8 7, correct single leaf mounts, correct traction bar bracket, stamped BJ 06 13 G2 in the correct location. It has 2.73 open gears in it, gears have no markings or stampings at all. Without a doubt it is stamped BJ, I'm not reading it wrong. I know someone has been in it as the cover isn't original but was BJ for 2.73 open originally? My info shows codes starting with B used in 68 camaros, it is a late 67 model year axle.

Thanks

BJ is a 67 307 open

That one is not seen very often but I know of one other on a 67 pace car.
