Does anybody know where I can find info on what speedometer gear I need based on tranny (700R4), tires (245/50/16), and rear end (3.23 posi)?

I assumed it was cable driven. You have 3 options of combination.
15T Grey (8642620) Drive - 39T Brown (1359273) Driven
16T Blue (8640518) Drive - 42T Green (1362049) Driven
17T Red (8640517) Drive - 44T DK. Grey (9780470) Driven

RMK: Thanks for the info. Is there someplace on the web that has info listed for other tire sizes so that if I need it in the future I can find it? Thanks again.

http://novaresource.org/speedo.htm uses tire diameter & rear end gear ratio to find what speedo gear ratio you need.
http://tciauto.com/tech_info/speedo_gears.htm has a calculator for tire diameter and has a chart of available gears for different transmissions.
http://www.bgsoflex.com/speedo1.html may also be helpful.
