bodydropping ford 2001 ford ranger

ok i pulled the dash out and now all i have left on the inside is the heater assembly so...do i get rid of all of that or can it stay i am not going to have any heat or ac any ways just wondering.

ya u might as well just pull it...dont take out that little box on the passenger side near the wall..its for your emergency fuel shut off switch..it wont start without it

heater/ac box has to go by by. i take it your traditional flooring it?
