Anyone know how to remove the dash vents from a 78 ford f-150 without breaking the tabs that hold the vents in?

 

I'm pretty sure these are the same as the F150/250 trucks, the Ford manual says to use an ice pick or small flat screwdriver to pull the tabs in from the inside of the vent and then wiggle the vent out. You can also remove the inside louvers with a thin screwdriver at the top & bottom and that might help to get to the tabs.

If you think they'll crack, a hair dryer will help to warm the plastic and that helps to prevent cracking.

 

Thanks. I'll try to be more careful. It seems those things are hard to get out!
