Need some AMC 304 intake specs...

[Granny]

I am preparing to do another TBI conversion, hopefully, in the near future. If anyone has access to an AMC 304 2 bbl manifold, I need to know the diameter of the throttle ports (big holes).

I checked an old rusted one at a junk yard and it was 1-5/8". NAPA's base gaskets have 1-3/4" holes. Since I am still driving the Jeep I don't want to pull the carburetor off until I am ready to make it happen. ThanX!!!

For reference...
