WTB Holley 6 barrel six pack center carb part

[pro-streeter]

I need help
Does anybody in the A12 six pack six barrel community have one of these ?
If so please PM me with price as I need one quickly. I am finding these 69 and 70 bowl vent arms are unique and do not interchange with other similar designs
The shape and how the end on both sides are bent seem to be unique to this vintage carburetor

This MIGHT be it. Not sure, no picture, call 'em.............

They also list a different one for the vapor return bowl.
