True Buly, except I don't know why prop hub thickness would be a factor or do you mean prop thickness at the hub?

Hi Tracy,
He'll need the the lug diameter and hole circle pattern, bolt size and prop hub thickness. I had to do the same and they came with all these questions, that I assumed is common knowledge?
Looks like the sales person has a form with all the questions he has to fill?
