Accelerator bushing

if thats the one with a steel rod going from the fire wall to carb with a 90 degree bend at the carb. chrysler calls it an insulator. but it does the same thing you are talking about. i did buy one in the mid 70s. due to odd angles a home repair might be hard to do. but does need to NOT hang up. dont know about an after market replacement. ill check out Dorman.
