@Reyser Hello again.
I managed to get everything working. Dials, lights etc. But I still have an issue with the tuning.
In LS customs it shows that bumpers, spoilers etc are there, but it does not up the name, or show the mod. Like in the image below.
In carcol.meta I've tried changing to both <kitName>965_fgt_modkit</kitName> to <kitName>965_bullet_modkit</kitName> & <name>fgt</name> to <name>bullet</name>. And in carvariation.meta I've changed <modelName>fgt</modelName> to <modelName>bullet</modelName>. But it remains the same. Everything else like "fgt_spoil_1" is untouched.
Thanks in advance.
