where is everyone going for speedometer driven gears? Older 727 ( but TCI modified). Looking for both ( for 4.10 gear ratio) 28 inch tire - 36 tooth ( called long I believe) red think O.E. number was 2538936. and will someday change to 30 inch tall - 39 tooth Green - 2538939. I have just started looking. and if I am not mistaken auto and manuals same gear. Thanks Jerry Horn
 
Should still be a couple of adverts in the Parts for Sale section. Possibly expired, but you can still PM the guys!

Mega Parts has a good selection as well. You'll need a want ad if you are looking for a used one. https://www.megapartsusa.com/search.php?nobox=&scat=&stext=speedometer&pg=1
 
For free you can use Speedbox (App Store download to phone). There are many, most have a basic version and upgraded elements. I use the free basic version and it’s spot on. GPS. I switch gears and tire sizes frequently so it’s nice to have an easy calibration tool.
