It's a 3.08.

You can download and run my VIN/Data decoder (found in the FAQ threads on this site).

Also, your tranny should have a metal tag on it. Use a cloth with a little gasoline on it to clean the tag off so you can read it. On this tag will be several codes. On the lower edge, starting at the left, should be the following:

3     08

That's the ratio of the rear end.

Door codes are worthless for finding out gear ratios. Mine said 3:18's and it had 3:40's. The tag on my '74 was located right on the rear axle cover bolt. After removing my cover, the rear tag was correct.

QuoteDoor codes are worthless for finding out gear ratios.

Well, both my Pintos were right on, so I wouldn't necessarily say "worthless." For those into numbers/code-abiding restorations, they're far from worthless.

However, the more accurate way to know what is actually in the vehicle is to look at the metal tag on the rear end itself (which both you and I suggest). Even so, the internals could have been swapped.

Short of removing the cover, I'd go with the tag unless/until you notice a disparity.
