Heres a few pictures I got on fabo. 73 Dart Sport 340. Im working on a 73 Duster, converting the 318 from 2bbl to 4bbl using a 73 TQ intake and 73 TQ carb. Looks like I have the correct bracket but the upper linkage I have is incorrect. Not sure about the lower linkage. Im thinking it may be the same 2bbl/4bbl
