Easy one, I think

I'm removing the EGR off my Edelbrock 2186 intake. The throttle adapter my 1407 carb needs is hitting it. I know the 2186 came with some EGR block off plugs, but who knows what I did with them. I'm sure I'll find them after I buy some. Can someone tell me the size of plugs I need?

Thanks!

I believe they are 3/8" NPT (tapered pipe threads).
