If you have or had an original 1969 Z/28 and know the transmission type and axle ratio please answer.

The 3.73:1 rear axle was the ratio you got unless something else was checked on the order form.
The other axle options were economy, performance, and special where you specified in the ratio.

BE or BV or QY is 4.10 ratio.

I voted "4.11 rear" since it's the closest one, and I have a BV code with a M21.

Not quite sure what you mean. 4.11 is not an option from the factory or in the poll.

Not for this purpose. I suspect the percentage of posi units is high due to Chevy recommending it with the 3.73 and requiring it with the 4.10 and above.

Thanks for fixing it.  Google's cache shows it before the fix: http://webcache.googleusercontent.com/search?q=cache%3Ahttp%3A%2F%2Fwww.camaros.org%2Fforum%2Findex.php%3Ftopic%3D11532.0&rlz=1C1BLWB_enUS541US562&oq=cache%3Ahttp%3A%2F%2Fwww.camaros.org%2Fforum%2Findex.php%3Ftopic%3D11532.0&aqs=chrome..69i57j69i58.6788j0j4&sourceid=chrome&espv=210&es_sm=93&ie=UTF-8

Thanks Kurt. I forget sometimes there is a small difference between 10 and 12 bolt ratios like 3.08/3.07 and 4.11/4.10.

BTW if you have a special ratio feel free to post it. The poll would get way to complicated if I tried to include all possibilities.
