1973 340 Carter AVS Carburetor 4 Speed

I am sorry , . I have a proper Carter carb manual , it says 1968 383 auto car only , yes Chrysler put them on 340, 383,413,s ect.My manual goes back to 1963 , and also theses AVS,S were used on General Motors back in the day. Sorry if i offended anybody, was only trying to help, i never mentioned one way or the other that there was anything wrong whit the unit itself.
