Review on 🚗 Perfit Zone Towing Mirror Pair Set: Replacement for 1999-2007 F250/F350/F450/F550 Super Duty & 01-05 Excursion Extendable Smoke Power Heated Side Mirrors with Signal Light by Hanson Kendrick

Thread stripped during tightening during installation. I noticed it first and coddled it with others. I couldn't squeeze them hard enough to close the gap from the outside without the threads starting to snap. I tried my best, but when I started expanding the mirror, all other threads failed at normal mirror expansion. Check the OEM against this thing in my picture. The main difference is in the quality. Everything looks and zero brown.
