Looking for a full set of (8) NOS AC Delco R44S Spark plugs in their boxes. Thank you.

 

Will R43S work?

 

I think they still make odd # plugs R43 R45 etc. They quit making them R44 heat range
I do have an extra set 8 nice clean old stock NOS pack of 8 individually boxes spark plugs and washers R44S boxes dated 1995
