67 barracuda switches

The wiper switch needed is determined by what wiper motor you have, 2 speed, variable 3 speed, etc...
Headlight switch, I wouldn't invest postage in a used one but... Since you do need a nice knob (bezel also?) maybe plan on moving those bits to a new switch in the near future.
Your hazard flasher switch application is a limited number of years. Good used are getting rare. Some have successfully took them apart and cleaned contacts etc.., to get them working again.
The climate controller is a one year only part. Two bolts hold it in the inst' panel housing. For 67, The left hand bolt is somewhat hidden between fan switch and the 2 sliders. They moved that bolt to left side of the fan switch for 68 up.
Unless you are absolutely sure it would be wise to check your cast pot metal inst' housing to confirm year model/bolt positions. Good luck
