Those appear to be the mechanical linkage carbs offered through DC and other sources- driver's side fuel inlets and no vacuum pods, unlike OEMs. From what I understand, basically Bowtie Tripower carbs. Your center carb may need the Holley/Mopar linkage adapter depending where the carbs were sourced, especially if you need to connect kickdown linkage for an automatic trans.

Fuel inlets and vacuum pods are on the passenger side. The original photo your referring to is of the driver side missing most of the mechanical linkage. This is all 100% mopar, but as stated in the original message, the linkage isn’t hooked up, it’s on my bench. The car is a four speed manual, so no kickdown. - Here is a photo of the passenger side with the hardline fuel rails / vacuum diaphragms.
