33 tooth speedo gear (i think)

hey guys
I changed out the rear end with a 8 3/4 which has 3.23 gears, and now when I'm doing 45 the speedo claims in doing 70
looks impressive, but rather useless

I run a 245/60-14 tire which the interwebs claims is 25.57 inches tall

If I round up that means I need a 33 tooth speedo gear

anyone have one laying around they want to part with?
