I took the 1” 1/4 to 2” adapter off my bike rack. When it was damaged by a car. And put a 1”1/4 stock steal drilled 2 holes and bolted it to the rack. Then took 2” stock and I slid over the 1” 1/4 stock steel And moved it back and forth until I liked it. I wielded it and now my rack hold 2 bikes and the swing out clear no issues and when I use it on my tundra it works perfect. The tail gate folds down and just enough room to get between.
