Spark Plugs

My LTR calls for AC Delco MR 43 LTS plugs. My local NAPA store ordered me some in and they said that this number has been discontinued and it is now just called #8. They look slightly different than the old ones. Are they really the same and without the MR designation I am wondering if they are a marine plug? Anyone else run into this?
