Choke question

[RPOLS3]

I have a Gen VI 454/425 crate motor in my Chevelle - it came with a modern version of the 163 aluminum intake (I painted it orange).

When I originally installed this I used a speed shop Holley with an electric choke. As part of a clean up and update project I am now installing a more appropriate Holley (4492) with a conventional choke. The issue I am having is that the standard issue GM choke assembly does not fit the pre-machined location on the intake - am I missing something obvious or are there other options for this? Quick internet search did not reveal anything other than what I already have.

Thanks in advance.
