200 Amp Dual Alternator and the pulley problem

[Marc lvnv]

Hey guys
I have a question about the alternator and pulley for my 2008 1123 humvee I got an new manufactured dual alternator and I bought a pulley for it what I thought it was the right one but the nut is not going on because it is not enough tread
Looks like it is the wrong pulley or what is wrong
I tried to find in the internet but no luck
Maybe someone of you guys knows

Need to see what eng. you have...an early or late serp belt system.
The nut for that pully is a double system for the late serp system with the black round reservoir above left valve cover.
The early serp system has the hidden power steering pump and alternator takes a different pully.
