Are these Toyota Tacoma 2018 CBI Rock sliders I received DCLB or DCSB?

I ordered Trail Bolt on Rock Sliders DOM for my 2018 Toyota Tacoma 4x4 TRD. It is short bed, (5ft), double cab. When they arrived, the brackets do not line up with the cross member. I am wondering if they accidentally sent DCLB instead of the DCSB. How can I determine which model I actually received? Will measurements indicate model? I am awaiting CBI in Idaho to respond with a solution but would like to be prepared with proof they are wrong set. Hoping they will send correct set at their expense. Any info helpful.

 

sorry for the the dead thread resurrection...you ever figure out the measurements? Similar situation but the other way around, I have the DCLB
