Drive Gear and Speedo Gear

I have a 90 5.0 Automatic Transmission and swapping out gears to 3.73. Which speedo gear and drive gear do I need to achieve an accurate speedometer? Or can I use existing drive gear and replace speedo?

The factory internal gear is an 8 tooth, so with 3.73's assuming your tire size is close to stock, you will need part number LRS-17271j-k which is a 23 tooth.
