ME AGAIN

Drove my 55 F350 to town and back. But when I got home my rear axle was dripping oil and had sprayed oil over the underside of my flatbed. Got the flange off, had an argument with the castle nut but I won I need to replace it. Took off the seal retainer and took the seal out; it had the following number A-1205-G-683, from my manual the Ford #7EQH4676 (I think), the gasket #B6QH4507-A, Axle vent 8A 4022, Castle nut 351165S8MM85. Now I'm trying to find the parts with no luck. Anyone, know who I can order parts from?

Can't help with the parts but are you sure your vent is good ? The absolutely first thing to check when you have a diff leak is the vent . plugged vent + heated oil = leak . the oil will exit at he weakest point

Thanks EBEAR, I'm also changing out the vent. But the seal is very worn and needs replaced too.

Are you looking at Parts List #72 in the parts CD? In there, I see seal p/n TCAA-4676-A, nut p/n 351159, 7/8"-20. Found the seal on eBay:
Ford rear seal #TCAA4676A plain encased O.D. = 3.06" & I.D. = 2.17" | eBay

NAPA also shows to sell it,

Yes, I was looking at my CD. The castle nut on mine is 1 1/4 inch - 20, although the CD says its 1" - 20. The pinion threads are 7/8" - 20.

Thanks for finding the seal on ebay and napa! I'll check napa tomorrow and see if they have the gasket and a nut.
