Fenderside Taillight Bracket Space

[Ryanz]

I am in the process of finishing our rebuild of 71 GMC Fenderside 4x4. The new box sides only came with holes for the reverse light brackets, not the taillights.

Would someone be able to measure the distance between the 2 brackets. I just need from top of reverse light bracket to bottom of the taillight bracket. I will post some updated pictures of our build later this week.

Thanks kindly,
ryan
