Searching for good used GEBE or Grubee rear engine mount bracket

Hello forum members,

I have been looking for either a Grubee brand(preferred) rear engine mounting bracket with all attaching hardware,or the GEBE brand engine mounting bracket with or without the wheel spoke driven HTD pulley ring,but
can not find any locally!!

If anyone knows where I might find a good used Grubee or GEBE engine mounts,I would appreciate replies with links or other sources!!
