Friday Night Show and Tell

I realize this is an old thread but having two 1972 H code 340 dusters one of them a four-speed (tx9 w/white bucket seat interior) both of them needing carburetors who do I talk to? I have a third one that's my Frankenstein that it's going to need a transmission, 904, both things that I've seen in this thread now... 6138s & 6139s
