hello after nearly 4 years (can't believe time has gone by that fast. anyways i decided to remake my sandy shores sheriff station garage mod (because i was not to proud of the original one. alright how to install the sandy shores sheriff garage remake. 
things you need 1:scripthook v 1:menyoo trainer or you can install it as a ymap by using Map Editor & Menyoo to YMap Converter.
okay here is how to install. first choose which one you want ymap or menyoo verison.
okay how to install for menyoo:1 go back to your gta v directory and click >menyoostuff>spooner. and drag sandyshore police garage to your spooner folder. how to install for ymap. 1:put sandyshore police garage.ymap in custom_maps in dlcpacks. add <Item>dlcpacks:/custom_maps/</Item> to dlclist.
after that launch gta v storymode and the game should launch press f8 when the game
is launched to open menyoo trainer. go to>object spooner >manage saved files and the file should be in there 
then click>load placements and it should spawn in. in the case of ymap the garage should appear at the sandyshores police station.
and yes you can absolutely convert this to work with fivem. anyways enjoy the remake of a old mod for 2024.
