Attempting to remove dash from '97 EVC. I have removed every screw, nut, clip and bolt I can see (and some that I could not), both inside the van and on the firewall. Edge of dash closest to passenger compartment is loose and lifts up, but I still cannot get it loose from the area under the windshield. Any suggestions? (the oft-mentioned set of youtube videos is for an earlier model, and they do not help.)
