DB4 # 00491 Transaxel Cover/Mold/Part

Rear transaxel cover as delivered in 1991 on DB4's. Anyone? A very simple part to reproduce if a mold is available , or if an original is available I can make a splash mold or is there one for sale. Any help appreciated. ( Has anyone heard from Tim Lamkin , DB4Tim )
Thanks,
