16 tooth gear here.

Mustang Speedometer Recalibration Gear - Manual - 16 Tooth (1983-1998)

Once you change the gears in your differential, you need a new speedometer gear to recalibrate your speedometer. They're inexpensive, and only take a few minutes to change.

Looking for the 15 tooth. I’d have to imagine tons of folks have them setting in their tool boxes as they swapped from 2.73s to better gears. I still have the gear for my AOD with 2.73s.

Everything I’ve found suggests the 2.73 manual cars with the 7-tooth came with a 16 tooth gear. Let me dig a bit more

Here’s a 16 tooth on eBay. I see plenty of them.

Cannot find a 15 tooth at all. I can find references to it in some of the classic mustang forums, but cannot find a single one for sale.

Chart doesn’t show a 15 tooth

Got it fixed. It took a 19 tooth pink gear to correct the issue. Thanks for the help guys, much appreciated.
Now on to fix the cruise and interior lights.

You have an aftermarket radio Matt88Vert?
People wiring stereos have a bad habit on Fords to hook up to the illumination wire behind the dash for the factory radio
Check that first if it keeps blowing the 5 amp fuse

No its OEM. my issue is the lights on mirror will not go off. I pulled fuse awhile back. I am thinking its going to be one of the door switches needing replaced. But haven't had time to check it yet. Quick check pushing them in with door open didn't shut lights off.

Those map? lights on the mirror? should have a switch somewhere?
The dome and floor lights are on when the door switches ground

The lights for the vanity mirrors on the sun visors must have the hard flap covers in place and be in good shape. There is a switch next to the mirror that is activated when the mirror is uncovered.

That makes no sense, unless you have changed you tire size or rear gear ratio.
