called a cowl panel and good luck tryin 2 find one my local ford stealership wanted about 230 for one and i found it nearly impossible 2 find one from a 99-04 body style so i ended up getting one from a 98 looks close enough for me.
I need one of these too. I was leaning on it, two separate incidences and I cracked it trying to shammy/dry/do something to my windshield. Both sides. Nothing too major, just looks weird having cracks on both sides. lol
