It could be any of these:-
39mm Stock 7.000"
39mm Mid-Glide 8.437"
39mm Wide-Glide 9.875"

Without a guide of some sort it's impossible to accurately measure centre to centre, IMO. Measure from an edge to same edge instead.

One would hope someone is not trying to fabricate something based off a measurement from someone elses bike off a forum. Harley is not exactly known for consistency. Harley's qaulity control philosophy is....
