68 Barracuda headliner rods

Okay, my headliner is in so I'm estimating on the measurements of the rods. Starting at the windshield it looks like the first (front) rod is 48". From there moving toward the rear the rods get longer. It looks like at about 1" increments (49",50". . .) Again, I'm estimating the best I can with a measuring tape. Hope this helps.
