The 2 panels going between the driver and passenger on the transmission tunnel are held by plastic clips molded into the panels and some tape strips. There are also 2 pushpins holding the top of the trans tunnel covers up under the two dash cover pieces each side of the windshield mount. IIRC, the safest way to remove them is to carefully lift straight up, starting from the rear, until you feel the tape give way. Each panel also has a large plastic clip molded into it up near the radio cubby area and after lifting and freeing the rear portion pf the panel, you then need to pull back on the panel to free the large clip. Use caution just in case I remembered incorrectly.
Yeah. I forgot to mention my MadStad Adjustable shield needs to be either raised out of the way or removed ion order to clear the two top dash covers when they are removed.
