Mike,
in your searching, would you mind letting me know if you come across the bakelite Urraco air inlet - item 44 in Luke's diagram, Lambo part number 4708845? I need one (PO crushed it) and am not having much luck. Thanks!!!
Eurospares has a P250 they are parting out, but it does not have the air inlet - not sure about the heater core. Keep trying them, they will answer.
Regards,
Bryan
