HOLLEY 1920 Accelerator Rod Bushing

The square bushing with hole for the throttle rod on my Holley 1920 carb has gone missing.

The bushing fits into a square holed bracket on the firewall side of the installed carb. Looks like a clip holds the throttle rod in place on the exit side of the bushing. It is probably just over 1" square with the round hole for the rod in the center.

Anyone out there have a spare?

This is on a 65 Dart with Slant Six. The engine is probably from the early 70's but the throttle linkage seems original to the 65 vehicle.
