Elliot, good pix...thx for posting
The red 917 was an outstanding clone, the importer ( cars are from Australlia ?) says it was headed for some sorting out, shift linkage etc.
Power is a weber'd 2.4 with a standard front fan. The "Flat " fan on top appeared to be an electric exhaust type fan, and just there for the sake of being there.
I don't think that the kind of money these will be selling for, another $10,000 would be an obstacle for a functioning fan. The Porsche horiz fan is totally bolt-on too
