373 Gears

What was it before? Ask a math major. OR, better yet

Simply get on the interstate and note odo reading at a mile marker then see what it is ten miles later. TEN miles to deal with error due to placement of marker or parallax error on your part.

If the odo reading is 1 mile off, then your speedo and odo are off 10%

Everyone should do this, anyway

Better yet, just get the blue drive gear fot the speedo and install it in the transmission. Why didn't the guy doing the installation mention it??? If you use someone who has done Mustangs he should have said something.

this is what i used with my 3.73 gears

Thanks for all the insite. I will surely try this out.

You can get this from your ford dealer.

I thought I could get this from my local Ford dealer... I got refereed to "someone who knows how to fix speedometers.... you might try the internet...."

Just like I thought I could get information on a mini-spare that would work with my car, since I changed the tire size from 14 to 16 inch, from tire places like Goodyear, etc... Same deal... "you should contact a Ford dealer..." who in turn told me "find someone who knows..."

It's getting harder and harder to find places where there is any real knowledge that isn't spewed out by a computer.
