I REMOVED THE THROTTLE BRACKET & DRILLED HOLE IN FIREWALL WITH HOLESAW @ INSTALLED FROM INSIDE THE CAR BRACKET COVERED THE HOLE

First time I seen that trick was on a new 88 F150. The feast plug was leaking. I’m pretty sure the guy pulled the carpet down and out of the way. He changed it from the inside in about an hour. Kim
