Needing grub customizer for 13.1

I like my SUSE 13.1 and it runs the video software I own,
so I really don’t want to upgrade yet.
But I need to delete several of the boot selections with
Grub Customizer and I cannot seem to find the older
version of grub-customizer.ymp for 13.1
Can anyone help here ? Is there a legacy repository I can
find this one ?
