Please help!! Looking for a SWB stepside bed for my 1966. I found a 67-72 in real nice shape. I'm told that the "BOX" of the stepside is the same all the way up to '86, but the fenders are all different. Will 66 fenders work?? I see that the 67-72 has marker lights on the side of the well and an emboss ridge also. Thanks!!

Also, what fits well in the way of a tilt wheel in my 66??
Thanks again!!
