Scania Streamline interior problem

[SirVirgoTheMess]

Hello,this problem has been here since long time.With the Scania Streamline,if we select normal cab,we can't select V8 interior(only the V8 steering is selectable).But,with Highline and Topline cabs,both V8 steering and interior is selectable.

Normal cab

As you can see,with normal cab,no V8 interior

Now,Highline cab

With Highline and Topline cabs,V8 interior is available

Thanks in advance!

The problem is the auto-equiping V8 interior on normal cab
