I thought a 12 bolt came in any 1970 Camaro with any engine that had a 4bbl, but the 3:73
ratio was standard on the Z-28 with the 4:10 optional. I do not know about the L-78 in 1970, so my vote is it came out a 1970 Z-28. Bill |

Correct Bill...only the Z28 could have gotten the 3.73s. L78s were 3.55 std and 4.10 optional.

The COZ 3.73 12-Bolt was fitted to all '70 Trans Ams with the M21 4-speed, or M20 and M40 cars with the Performance Axle option.
Also available on '70 Formulas. My RA III / M21 Formula has a COZ. |

If he decides to advertise it, I'll let you all know. I won't be buying it.
