Hello, I just had my Autolite 2100 carb rebuilt by Carburetor USA and for anyone interested, I highly recommend their services.  I do have a question though before I install.  My phenolic spacer does not have 2 distinct holes under each throttle plate, rather they are conjoined similar to this example:



The new flange gasket I have has two distinct holes:

I assume I would trim this gasket to fit the contour of the spacer, correct?

Finally, some examples have three additional small holes punched in the material as this example:


Can you folks give any insight as to which gasket would be the correct one to use?  Thanks for your help
