The story I find most believable on why these dashes crack is the plastic was not formulated correctly. Not enough UV stabilizer allows the sun to leach the oils out of it making it brittle....
Looking at them, I'd have to agree.
However, I do find fewer cracked/broken dashes that APPEAR to have never had armor all on them.
Armor all is detrimental, it actually draws away the oils and stabilizers in plastics, sure it LOOKS good when it's on there, but, IMO, it actually adds nothing in the way of protection.
As far as removing the dash tops, I can have one out of the truck in about 45 minutes to an hour.

Yeah, I've wasted a lot of time pulling them, so much so that I have a routine down. LOL
Several I have pulled weren't cracked when I started, but I heard a small "snap" and they ALL cracked at the vents.
That area is where it all starts, because it's the thinnest area and has the most direct sunlight.
FWIW, usually the pre-1998 dashes lasted a lot longer.
I will add that I have only ever seen one early RED one survive and all of the early BLUE ones are garbage by now.
