try to support the middle speaker while you're in there if you can.
I don’t have one of those otherwise I’m sure it would be cracked around it. I will add reinforcement like I did on the new one I put into my Silverado, using 1/8’ steel rounds and epoxy in the areas of the cracks. That is of course if the thing isn’t too brittle but I’ll know when I remove the front piece by the windshield. If the areas where those clips pop into the dash start to break I’ll stop right there.

Ever since my engine was replaced I am getting some rich cold starts and even some flooding. No engine lights or codes whatsoever. Only happens first thing in the morning with temps in the 30's and below.

Do you have a tune in your pcm? Might need a cold start retune.
