Axle Ratio

[charlie268]

Quick question? On the door jam of my truck where the codes for different things are is an axle code of 97. I think when I checked it on the chart it showed an F7. Then I found this to be the nonslip or like us old farts used to call it positraction. What is a 97? I assumed it was a 410 that wasnt nonslip!!

a 97 is an open 8.8" with 4.10 gears. R7 would be 4.10 with limited slip. F7 would be a 7/5'' axle with limited slip.
