Spark plugs

I own a 55 Ninety-eight and want to replace the spark plugs. I think it originally came with ac brand 45s. Is that plug still available if not what would be a replacement? Thanks

It came originally with AC Delco 44. They are no longer being produced.
If originality is not needed, these should work:

Found these on ebay.

http://www.ebay.com/itm/AC-44-Spark-Plugs-/252092992932

They are listed at $34.99 with no bids and a day and a half left on the auction. Worth a shot. Shipping is $5.95
