Can I ask why specifically that plate? Or would one from the same era suffice for your interest?
Macarthur Jobs Air Disaster Vol1 details a similar Pan Am 707 accident around the same time, this one at Pago Pago where there is a copy of the plate for that approach. No reference to your accident has a copy of the plate you mention.
I can scan the plate for Pago if you want but that's not what you asked for.
