part knowledge

End of speedo cable that hooks into 700-4 transmission on my S-10 chassis. Gear was stripped and that turns the speedometer in the truck.

Used a GPS based speedometer app on a smart phone to test

My speedo in my 1972 Corvette read about 10mph fast. I had a 21 tooth gear and went to this 18 tooth gear, speedo now reads within 3mph. Used a GPS based speedometer app on a smart phone to test.

Exactly What I Needed

My GMC Van needs a mechanical speedometer driven gear, Couldn't believe it....there it was....Same color and all...wow... The color is very important 'cause each of the many gears has differnt number of teeth and the color determines the number of teeth. Thanks good job
