Center A/C vent

How may I ask do you attach the center vent A/C grill and the box to get the air to it ?

The Grill has two posts that go through the box, then the hose attaches to the box.

There are 2 pieces to the center vent. The part you see on the dash and then the part inside the dash. The part you see has 2 studs made into it that go through holes on the plastic part behind the dash with nuts which sandwich the dash between them. Then the two hoses that connect it to the inside dash box on the passenger side of the truck.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

I think they are 1/4" 20 studs. Some all thread rod should do the trick.

I found with mine that if I balanced on my head and placed both feet into the rear corners of the cab it would leave my hands free to do the work. The system had to be designed by someone wearing a shirt and tie.. Good luck.

Yep, I had to do the same thing and while I was at it cleaned the vac motors and tested . reviewed the wiring ,
It took me 3 hrs and tons of pics to dissemble and 3 days to reassemble.

It's a big PITA for sure !

The biggest problem is the word FORD. With the Chevy's there is no room for actuators, it's more of a balancing act problem. Mine needs a shot of R12 but I can do that standing up. Have a good one eh.
