There are some generic choke coils that bolt to that. I have one on my large port dual plane Weiand intake.
iirc they come with the coil ends on either side. There is a pin that locates them but flipping them changes the offset of the coils.
can’t remember if they come in different opening rates.
the Tomco 9007 is for sure one. You can see the outline matched toolmanmike’s pic. Not sure is the Standard CV-76 is one. I think one has the lever attachment on the wrong side.
you’ll have to look it up those part numbers and figure which is right.
PS. Toolmanmike, is Champion Auto still in business ?
