I cannot get the dashboard to release. All bolts are out. I'm trying to replace the A/C core. Any hints on what's holding it on so tightly?

 

Did you remove the steering column? And/or the blower fan/box?

are there bolts in the front door jam where the A-pillar meets the front door hinges? There may be cross bolts in holding in the crash bar.

ive never done it in a SC430. But took my dash out from my 2014 LS460 and both of those components needed to be removed.
