Post ring gear numbers-9 inch ford

I've got a third member out of a 9 inch ford that I don't know what kind of gear ratio it has. There is no tag on the housing. I know that it is a 31 spline set up. The info stamped on the outer surface of the ring gear is: Ford USA D2AW 4210 AX2. The ring gear hub has stamped on it: C6AW 4205 B, and MCC 31. The third member housing has stamped on it : C7AW E 27. If anyone knows what gear ratio I have it would be helpful. The third member is in great shape and I would like to use it in my project. Thanks in advance. Mike

Yes you should be " MORE SENSATIVE "

Some whiner was on the other day about his poor mistreatment.......

Some folks do not need to work on their cars. I am always amazed at how some folks can be so computer literate and smart but when it comes to cars.........


I do fairly well with Snapon, Mac and the like......but with Dell, Windows andd the like .......I am so lacking the needed skills.
