1978 floor pans

[78stregis]

I have a friend without internet looking for driver floor pan for a 1978 New Yorker St Regis. I haven't been able to find replacements of even info on a "will fit". He would also be interested in lower panels between the rear quarter panel and trunk. He already has NOS quarter panels. Anyone able to help us?
Thanks!

I've ran into that problem on my '78 Yorker. Unfortunately these cars are pretty much non-existent when it comes to reproduction and aftermarket parts, meaning he'll likely have to find a parts cars to cut them out of, or fabricate his own

Or a trip to Sunny Arizona in a vehicle which can haul the needed parts securely out of sight.
