Way too cracked to cap?
You'ld be surprised if you saw some of the cracks under some of those caps. You cut them all out to install a cap anyway. Let's see hmmm $85 dollars or $700 dollars? Hmmm
To pull the dash, Pull out the steering column, pull out the long studs that held the column up, disconnect and unscrew the fusebox from the firewall, pull the speedo cable, unplug the A/C vacuum lines at the switch (if app). disconnect any other wire from the dash to firewall, take off both pillar side covers, remove both foot side panels, unplug antenna plug, use a small 1/4 inch ratchet with a u-joint and long extensions to remove the 4 bolts on each side of the defroster vents, loosen the 2 lower dash bolts on the lower front corners by the doors, drop the dash to the seat.
When reinstalling, I've found that it is easier to start the defroster bolts if you have the inst. cluster out because you can guide the clips to the screws.
