Gear Ratio in 2006 Corvette File

[superls1]

The 'Final Drive Ratio' shows a value of '1'. I downloaded another stock file it also has a value of '1'. Installed some 4.10's in this vette. I was concerned because help/description indicates should/could be something like '2.73, 3.42, 4.10, ...'. So, I it seems like I should change it to 4.10, but why is it '1'? Just making sure I am doing this correctly.

The speed is picked up off the center section at the 1/2 shafts. Unless there is a tire size change there is no reason to change anything in the speedo section on a manual trans Vette. You get to pick the shift speed.
