RE: SPEEDOMETER GEAR

Have a look at this article on gear swaps....about 3/4 of the way down it explains speedo gear changes and has a chart.

1990 AOD w/ 3.73 bought the 21 tooth from 5.0resto for ten bucks, really need a 23 tooth but its barely off, maybe 2-3 mph, i didn't bother changing the drive gear from a 8 tooth to a 7 tooth. Great Mod

I read this question last night and it took me along time to find a chart that I had. Hope this helps.
