Leer 100xq Roof Rack Rail Location

I’m about to drill holes in a Leer 100xq and I can’t find any info from Leer as to allowable placement of the rails. I have a 2014 double cab short bed. Does anyone have a cap with factory installed rails they can measure? I’ve heard the caps are not solid fiberglass and rails need to be at a specific width. Thanks in advance.

There are multiple write ups.

 

You should talk to a Leer dealer about this. Your cap may not have been manufactured with the internal support for a roof rack since it was not ordered that way from Leer.

I have a Leer 100 with factory installed Thule rails. I could get measurements later tonight if needed...
