HELP! what speedometer gear do i need

I need some help finding out what speedometer gear i need. Its an 82 c10 t 350 tans. 273 gears. 31 inch tall tire. Is there a chart or calculation to come up with the correct speedo gear. And is this a dealer only item or who else would have them ? A part number would be great.
Thanks for the help. Ryan

Use all the gear combos and fill in the blanks

Find a combo with the closest whole number.
