Nerf bar help , identifying Tahoe??
 

I need help identifying a set of nerf bars that I bought.
99-07 they mount to body mounts 75" c/l bolt hole to c/l bolt hole.
I have a set on my 2001 extended cab Silverado. My sister wanted a set for her 2002 Seria crew cab, I found a set they were longer than the ones for my truck.
Figured they had to be for a crew cab. I see her about once a month, so didn't have time to measure her cab mounts.
I'm thinking they may be for a Tahoe??? If someone can measure their Tahoe mounts that would be appreciated.
