Need help with Gearing codes

Found this tag on my axle:

The upper numbers are V132C (not to sure thought)
and the lower ones are for sure 10 10 2 OC14

Also since I was under my truck, I wanted to check the gearing on the ZF5, I have trouble seing it cause the front drive shaft is in my way but where it says *Ratio* theres a few numbers that I can't really see but the last 3 digits are 0.77

Is this enough info to tell me what kinda gearing I got? If not I can go look again.

Thanks

What is the two character code on your driver side door tag under Axle say?

You can look up Ford axle codes here:

In the bottom row the first two numbers are 10, the 4 is under the bolt head.

L10 would have been the limited slip 4.10 axle.

next set is 10 2 which is a 10.25" ring gear.

With stock 235/85 tires, a 4.10 should turn 3300 at 74 MPH.
A 3.55 will turn 3300 at 85 MPH.

Are you sure you have a Dana?
Fill plug on the back cover of the differential?

Sterling fill plug on the drivers side of the pinion on the front of the differential.

They look almost identical, the fill plug location if the fastest give away.

I would bet that if it tachs out around 70 it is 4.10. My 84 t19 4.10 gears tachs out at 72. My 84 with 3.55 will run way past the end of the speedo(85).
