front wheel bearing dust cap part number...

[Georgboy]

Hey guys new here from Ga . I have a 90 d250 178k miles pump turned a little otherwise stock....I have been trying to work a couple of bugs out of the truck and that is going well by all the info I have learned here, but I seem to have an oddball size front wheel bearing dust cap on both front wheels...they are larger than the dust cap I have ordered from parts store and two 3/4 ton trucks that I have found them on at the local pull apart ....please share the part number of the correct size if you have it...thanks guys...

With the 4000 pound front axle they do not make it anymore.

But, the cap is the exact same size as a 5200 pound trailer axle. northern Tool, Farm and Fleet, Tractor Supply all carry them, they are a perfect match.
