Is a 66 wagon diff and a 66 2dr ht the same? width, size? The wagon diff has 3.42 gears in it. I didnt think you could get that ratio in a 8.2. Did they make a 8.5 as early as 66?

I'm new here. This is my first post. I have a 66 ht that my sons and I are building into a bracket racer. It was a rough condition rolling shell.

Thanks,
Mark

Thanks, Great info. I'll check and see why the ratio is 3.42. Maybe someone swapped the diff.

My 6cyl Powerglide 1964 wagon came with 3.36 gears. I think the manual trans cars may have come with a little more gear to help the clutches last longer, but I don't think I've ever heard of a factory 3.42 in a first or second gen NOVA.

If you have 3.42 gears maybe someone has swapped in a 8.5 rear.
