It Did and Did Not Work
My truck is a 2024 Chevrolet Silverado 1500 WT. The mount I received was "12-3403 Chevy / GMC Silverado 1500, 2500, 3500 Hood / Fender Antenna Mount & Coax 2019+". Walcott Radio later confirmed that I had received the correct mount. The photos included in the instructions did not match. I tried anyway. It was close but would work unless I was willing to do some serious clearance grinding to it. On a whim I decided to try it on the passenger side. I fit and cleared the hood perfectly! I am convinced I got the wrong mount (one for an earlier model?) and informed Walcott they needed to check these. I am just glad it worked in the end.
