Where to get speedometer gears
I need the complete driven assembly for a 3.70 gear rear with a T-5. Where can I find this?

When I need speedo gear drives I go to the local GM dealer they are most helpfull.
The info you will need is transmition type along with serial numbers to make sure, rear end ratio and tire size, the dealer is always very helpfull with thng like this.

I used a 7 tooth drive gear and a 20 tooth driven gear for my T5 and 3.70 gears, with 255/50-16" tires. You can still get the speedo gears from the dealer.
