Anyone know what size threads the 3 trumpet base take offs are, for the brake servo, carbon canister extra?

Cheers! I take it all three are the same? I need to blank two of them off.

Plenum-trumpet base M8

Trumpet Base vacuum tappings on the side are 5/8"UNF

Trumpet base - Inlet manifold 5/16"UNC x2.25" long (add insulator thickness)

Apologies i stand corrected. I have obviously been given some recent duff info.
