'02 lq4 intake brake fitting for vaccum style '99 tahoe

Hey guys I've got a 2002 lq4 I'm putting in my '99 OBS Tahoe and I was wondering if any of y'all know the P/N I need for the fitting that goes on the lq4 intake that will allow me to hook up my line running from my brake booster. I tried looking it up somewhere and found a PN 12555831 but come to find out it's the exact same fitting that I already had on my stock '99 intake, I need the fitting that will fit into the lq4 intake and mount up to my vaccum line.

For anyone wondering what the part number is for this it's 12559760
