Get an alternative that can be gapped.  Is there not a non-platinum BPR6?
Champion N9Y or its derivatives (e.g. RN9Y, RN9YC etc)  .035 is the
recommendation for all rubber bumper cars, probably something to do with a
change in coil spec and a fatter spark for emissions cars.

You should be able to get replacements for those - unless you want to change
the fusebox type as well, but there's nothing wrong with them that can't be
put down to 25 years and POs.
