[Chevelle-list] Gear Ratio.

[dgage]

Can one of you guys tell me what gear ratio I have. And what series
carrier I have.  It's a 12 bolt rear end in a 1968 Chevelle SS. The
numbers on the ring gear are  12  67  3853003-14-43   The pinion gear has
14 teeth. The ring gear has 43 teeth. I'm thinking 325 or 307 gear ratios
but GM didn't offer those ratios that I can find. They offered a 308 but
the math does not point to that either.
 Thanks ahead of time for any help....Dennis
