engine sump oil cooler fitting size

[belenjack]

i am doing an engine overhaul on a 67 four cylinder ex mod on the sump just forward of the drain plug there is banjo fitting for an oil cooler the flex tubing is pinched off i want to install a plug instead can anyone tell me what size this fitting is? i tried a 3/8 bspp plug but its too large

Isn't it the same as the sump drain plug? Or is that one 3/8 BSPP?

I believe the number is ERC3315 Plug, priced at $13.28, part is "Special Order".

Please advise.
