250 Cross Flow in a 64 Econoline Pickup

[Ranchwagon]

I have what I think is 76/77 Aussie Ford Cross Flow w/C4 installEd in A64 Econoline Pickup.
I rebuilt the engine runs great but the rear main seal has failed after very miles. Does anyone know of an American source.
I believe it is the larger seal

Its the same as a US250 rope rear main.

First, I think the engine 1981/87
Second, what came out of it is a rubber lip seal 4.330 dia.

What's the casting code on the block?
If it has the 76 block, you can use the two piece rubber lip seal making sure you remove the pin for the rope seal first.
