Super 6 Set UP

I am being offered a Super 6 intake, carburetor, and air cleaner from a 225 slant with a 4 speed manual attached. Will this be a problem installing on my 64 Dart GT with 225 and 904 pushbutton transmission. What do I need for an easy install? I am concerned about the kickdown linkage, will this be a problem? I do believe that my factory exhaust manifold does not need to be changed. Should I ask for all of the mounting hardware. And, what should I offer the seller for a fair price?
Just convert it to. 4 speed. Better mileage and more fun. But yeah it will not work you will need to swap over to the lokar set up. No kick down linkage you'll fry the trans in a couple of months, What ever you do buchollion set will not work it only works on 67 and up with four barrels, you have to modify the floor and bracket to make it work on the early abody with two barrels waste of time.
