Heyho,
I got a new mod for you.
It replaces the Vinewood Plaza into Hollywood Plaza including 247 sign to 7 eleven + other real brands and one billboard

Install:
go to GTAV\mods\x64j.rpf\levels\gta5\_citye\hollywood_01\hw1_07.rpf\
and replace 
hw1_07_wtrbuild05d+hidr.ytd
hw1_07_wtrbuild05d.ydr
hw1_07_vw_muzak_001+hidr.ytd
hw1_07_vw_muzak_001.ydr

go to: GTAV\mods\x64j.rpf\levels\gta5\_citye\hollywood_01\hollywood.rpf\
and replace: hw1_07_slod1b_children.ydd

if you use my "Fresh real brand billboards" mod https://de.gta5-mods.com/misc/fresh-real-brand-billboards-for-the-gta-5-universe
open hw1_07_lod.ytd and replace the hw1_07_billboardlod file and the hw1_07_wall_001_lod from the iodmybillboardmod folder

if you use the vanilla version 
open hw1_07_lod.ytd and replace the hw1_07_billboardlod file and the hw1_07_wall_001_lod from the iodvanilla folder

better save your files first before doing any changes

please let me know if this works for you

greets,
mike
