Need help finding 1/500s for my father's model of SJU airport.

[SJU_RDU]

Hello everyone! My father is building a scale model of Luis Munoz Marin International Airport (SJU) set in the early 70's. He is looking for certain models of aircraft with late 60's to early 70's liveries (I have attached the specific ones he wants). Please if you yourself have any or know someone willing to part ways with one let me know.
I can only post 10 photos at time here are the other 4 i need. I'll send photos if you request them.
-Liat BAC 1-11
-Caribair DC 9-15
-Dominicana 727-200
-Delta DC 8-63

The models must be:
-1/500 die-cast
- In good condition
- Realistic landing gear
- late 60's early 70's liveries.

Please help me out if you can and do not hesitate to ask me questions. Thank you

I don't think these models were ever produced in 1:500 scale. You'll probably have to buy donor models and get them customized...
StarJets did the Delta DC-8, though: https://database.diecastmodelaircraft.com/model/9399

How far has he gotten with his project? If he's just starting, it might be better at this point to switch to 1:400 for much better model availability.

Thanks for replying. He is pretty far into it. He has most of the ones he needs including some rare ones.
