69 'HEMI' 302 crossram intake base

[iluv69s]

Been a while since I've tried, bit still looking for a needle in the haystack. Seeking Hemi 302 intake base for the chevy experimantal 'porcupine' aluminum small block head package made for the 69 Z28. These were made for the Trans-Am series cars, but never actually used. I have found two original top plates with the dual casted part numbers,(which is interchangeable with a normal crossram top plate) so I suspect there may be a base on someone's shelf that they do not know what it is for. Any leads appreciated !!! Thanks SYC
