Looks like a 21 tooth gear is what you'd need, as shown HERE.
'98 Explorer 5.0
'20 Malibu (I know, Chevy, but, 35MPG. Let's go brandon, eh)

if you can  get the gear from a 5speed t5 TC car, then you will be 3.5mph off the speedo will be slow
1985 TC (yet another one) Fully loaded
has 225k mile  still with the factory head gasket
