I just happened upon this thread. I had the same issue. I have a 2006 350z Touring 4sp vq35de Rev-up Prod Date: Nov 2006
The first Parts Store gave me a Gates K06065 ( 6pk1181 ) 13/16" x 47" Micro-V
It was too long and I could not take up the slack due to pully delete.
I brought that belt and they now gave me K060450 ( 6pk1146 ) 13/16" x 45 3/4" after matching up production date.
This fit but was very tight. I used a plastic panel removal tool to slide it over the p/s pully. I think a 46" might be the perfect fit, but I didn't try one.
I hope this helps!

Sorry about using inches instead of millimeters. I thought this was a US site. 🥴
