Need some help on this, I'm away from my bike and I need to order an 14" ape bar from road6customs with riser for my softail

I've the HD Inverted forks mounted on my softail P/N # 48646-06A
I was planning to put a slimline riser

Desc:
Slimline risers have 1-3/4” of rise as measured from the base of the riser to the centerline of the handlebar clamp

I know that the triple trees on a inverted forks are much beefier compared to the regular trees.
Anyone who is running the HD inverted fork setup, could you please tell me what is the size of riser should I purchase to set up my ape handlebar kit?

Apehanger that I'll be installing on my bike

Anyone here could help me on this as I dont have the bike near me and not able to find out what length riser that I need to buy to put on inverted forks

 

I had Carlini 14" Gangsters on my bike and I used their 1.5" bra risers.
