Need help with a stepside Taillight Measurement

[blkcorvair]

Maybe someone out there with a Stepside can help. I just mounted the new Triplus bed sides I have. Im a little dissapointed they dont have holes for the Rev Light or Taillight Brackets! With no nuts welded to thew back side.

So it looks like I am going to have to use nut serts.

But I dont have my old bedsides for reference. I can locate the Rev light bracket using one hole that is there. But I need a measurement. Can someone get me a measeurement from the top of the Reverse light Bracket edge to the Bottom of the Taillight bracket edge on a stock Stepside???


It looks about 2-1/8" in a reference picture I have but wanna be sure before I start drilling. Thanks!!!!
