...but I'd suggest removing the speaker grille, and even the steering column brace, anything to make the job easier.
When completely disassembling my truck for restoration, for the life of me, I could not figure out how to remove the steering column brace. So, it was the only bolt in part that stayed put. The brace wont move reward to disengage studs from firewall. Can't move it sideways to disengage studs. Can't move it up to disengage studs...you get the idea.
