What year did Ford change bolt patterns on D60/Sterling10.25?

[F0rdFre@k]

I have a pair in my garage. Told they came from a late 80s/early 90s F350 Dually. I got a ring from a HMMWV wheel and it fit (8x6.5). So, just wondering if I could identify more closely what year these are out of?

TIA

The metric wheel pattern started in 1999 with the Super Dutys.

My '97 F350 has the 8x6.5.

91 and older Dana 60 would have kingpins.
newer would be balljoint.

Dana BOM number would be the best bet...

That helps. I know it's a Kingpin D60. What year did the 10.25 release?

10.25 came out mid 80's, around 84/85

Ford didn't change to metric till the SD'd. So if your pre 99 your good.

Although you could just measure the pattern on the axles:flipoff2:

I know the pattern is 8x6.5. I wanted to get a narrower idea of what year these came from. Since the PO's PO didn't know.

FUN!!!

Thanks all for the input.

Based on this info, I know these are from an 84/85-90 F350 Dually.

Now, to get rid of the long hubs on the D60 and find disk brake conversion for the 10.25. :D
