I went down to the local Ford dealer to order in a speedo drive gear that's compatible with the 3.73s installed in my 89 LX 5.0 5-speed and they had no clue what I was talking about. They said that if I could supply them with a part number, they'd try to get one.

So Fox guys, anyone know that proper speedo gear I need?

THANKS!!!

 

Cool, I found a chart at: http://www.muscularmustangs.com/gears.php

Red it is!

 

IF you call Downs Ford Motorsports, they will tell you also.

 

The just put in the red gear and it seems that my speedo is just about perfect now! Nice to not be crawling along doing 120 anymore!
