im changing blend door actuator motor. dash is loose and i think the only thing holding me up is the brake cable. theres a "union" under car that connects front and middle cable. can i pry that apart and pull my dash out enough to workbehind dash/in front of firewall, or maybe drill rivets that hold e brake assy to dash? any suggestions would be helpful. thanks p.s. undoing cable from pedal assy doesn't accomplish what i need.
