What's your point?
Most bus interior stuff has to be de-installed in the reverse order it was installed....
It's called the "layering effect"...
Gotta remember that Dina was built by a labor force that probably couldn't grasp the concept of
phillips head screws and screwdrivers. Just kidding
Actually many aircraft including military stuff uses and used flat blade screws. MCI used them in my MC9
in the oddest places and my old GMC 3102 and 4501 used then also even in structural fasteners.
Sorry, Just bored
