**Edited my answer** I took a look in a few of my older Fel-Pro catalogs and I didn’t see a listing for that gasket alone. Unfortunately I don’t have a new catalog, I don’t know if it’s listed separately there. I opened one of my Fel-Pro #2720 R*A*C*E ( Remainder to Assemble a Complete Engine ) gasket sets and pulled out the oil adapter gasket in the set and it’s numbered #70135. That appears to be a good Fel-Pro number for that gasket.
If it helps the Ford part number for the paper gasket is C0AZ-6A636-B, i don’t know if it’s still available new, been a while since I ordered some, but there are lots of them floating around.
Ford also had a rubber coated embossed steel version available, it’s part number D3TZ-6A636-A. I put an Internet picture below. The oil passage holes are shaped a little different to match the pickup truck oil adapters. I think I have one around here somewhere, but can’t find it at the moment, I was going to try holding it up to the typical car oil adapter and see if the passages work, but can’t verify right now. I don’t know if these are still available at the dealer, but again seems there are a bunch out there.
Here’s the D3TZ-6A636-A for those interested.
