Gen Y and Sierra 3500

[M and E]

I'm curious if anyone who owns a Sierra 3500, late model, know what mounting holes their Gen Y is aligned to (e.g. second hole down from top, third, etc.). I have Rhino pinbox on 25 340RL, but interested in any data you all have.

I have not yet received my gooseball and just trying to plan for a friend to come and help or if I'll have clearance.

Do you remember what your distance was from the top of your other gooseball to your bed rail on the ford?

When you get your new one, you should be able to calculate which, if any direction you need to move the Gen Y to maintain the same bed clearance.

Hope things are working out to your expectations so far with the new truck!

Only put a hundred miles on it so far but it is really impressive! Thank you!!
I want to say the sides were 19". I've got the puck in the garage so I can kind of estimate I guess.
