Love my truck...... why does my tag on the rear end say 3.25 yet definately says WDM BA 2 on the top line?

Have a look here and see what the difference in the gear ratio 3.20 and 3.50 would mean to your truck with your 27" rear tires Gear Ratio and Tire Size Calculator - 4x4 and Jeep Ring & Pinion As to why the conflict between the 2 ID's it's hard telling

Axle tag confusion

[img alt="I have this tag off axle of donor truck 77 F150. The WDM-BA2 on top line and 3 25 on bottom line have me confused. Is this a 3.50 non Linter slip or 3.25??

Another forum suggested this was a 3.55 gear with limited slip. I can’t find anything that back that up.
