Super 6 conversion

Does anybody know where I can get all the correct brackets and kick down linkage to do a super 6 conversion. My son was given a super 6 intake & 2 barrel carb. Started to do the conversion then hit a brick wall. Turns out he needs a few missing parts.
Or maybe what cars or trucks to look for. Any help would be appreciated.
Put a posting in the parts wanted section. The kick down linkage can be hard to find. Go with a Lokar cable kick down for a 904,
Installs and adjusts easy.
