    Back again! Lol. I have a question about finding out my dif gear ratios; how do I find this info (I have my VIN handy) on this site or online? The tags are missing off not one, but both difs! Any help is greatly appreciated. Thanks! Donnie

    The door tag should have an axle ratio code. Post it here.

    Okay, I have it here. Sorry it's so hard to read. It's faded, and my phone can doesn't have a flash.[emoji20]

    The pic is so blurry, the AXLE code is impossible to read. Type what it is.

    Okay. I'm on a job at the moment. I should be home in a couple hours--will that work?

    FTZKen, I just double-, then triple-checked, and I got the axle code right--it IS 18. All help is greatly appreciated![emoji4]

    18 = 1980/86 F100/150 & Bronco Ford 9" rear axle (no inspection cover) / 3.00-1

    18 = 1983/89 F100/150 & Bronco Ford 8.8" integral rear axle (has an inspection cover) / 3.08-1
