I got rid of my 91 E150 3 years ago and have regretted it, so I picked up a 85 E350 last night.
It is a 460, C6 Trans and I'm guessing a Dana 61 rear end, but I can't tell for sure.
I can't read the entire BOM stamp as the numbers are faded, I tried buffing them with a light scuff pad and even tried bringing out the numbers with chalk, no luck.
The only things that I can make out on the BOM stamping are:
CR8 X1 ZO C0887NA-1, but I can't be certain on these numbers.
There is an axle tag on the diff cover, but it is un-readable.
The VIN tag on the door frame states that the axle code is C3, as much as I search, on here and other sites, I can't find out what C3 is. Short of popping the cover off and measuring ring gear OD (maybe I got lucky and got a 10.5" Dana 70!) and counting teeth, anyone have any idea what this rear axle is?
