Speedo gear and cable

I have a 92 Ford Mustang 5.0 HO w/ AOD going into my project car.

I'm running 15 wheels, w/ 3.75 rear.

Does anyone out there know what speedo gear I need, where I can get it?

TR, try your Yellow Pages under the listing for Speedometers. If your book is like ours it will list any local businesses that cater to instrument repair and calibration. These firms usually have the equipment to manufacture "oddball" cables. If you find no such listing, check with a local and/or state police agency for a local speedometer calibration company.

Thanks!
I'll contact Mustang Unlimited.
Also Summitt Racing said they might have the cable for the Autometer speedo that I'm installing. I sold my old speedo and tach guages as I knew they would not work with the 5.0/AOD.

Bill, Sorry but I made a type-o!
The rear end is a 3.45

Would I use the same gear?

Cool

Thanks

I have ordered one from Mustang Unlimited!
