wpf xaml scrollbar

I'm trying to reduce the size of the scrollbar control and make it more "Apple" like since it would fit my interface really well.

What I'm trying to achieve is something that looks like this:

enter image description here

So far all I have is this

        <Style TargetType="{x:Type ScrollBar}">
            <Setter Property="Stylus.IsFlicksEnabled" Value="True" />
            <Setter Property="Background" Value="#8C8C8C" />
            <Setter Property="Width" Value="8"/>
            <Setter Property="MinWidth" Value="8" />
        </Style>

Working XAML

It's not very pretty and in all honesty I can't remember where it came from, there is something similar to what you're after in one of my project here, there is probably a lot in the style that's not required or is incorrect but may as well give it a shot.

 <!--Scrollbar Thumbs-->
        <Style x:Key="ScrollThumbs" TargetType="{x:Type Thumb}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Thumb}">
                        <Grid x:Name="Grid">
                            <Rectangle HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" Fill="Transparent" />
                            <Border x:Name="Rectangle1" CornerRadius="10" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto"  Background="{TemplateBinding Background}" />
                        </Grid>
                        <ControlTemplate.Triggers>
                            <Trigger Property="Tag" Value="Horizontal">
                                <Setter TargetName="Rectangle1" Property="Width" Value="Auto" />
                                <Setter TargetName="Rectangle1" Property="Height" Value="7" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
