2-Barrel to 4-Barrel Conversion

Mike thanks for the info. I could not find the Mancini one listed in the feed but found this one:
1968-1973 All Makes All Models Parts | MF224 | 1968-73 Mopar 340 Four-Barrel Throttle Cable Mounting Bracket | Classic Industries

Looks the same as the one in the discussion you listed. Let me know if I am wrong.
