They should look the same for the most part. At the IFRC Nationals last week all the 58's I saw the mats and boards looked the same. A few of those were recent restorations. I ordered mine a couple of years ago and and they looked drastically different. Sent them back and got a new set and they were fine. I usually deal with Toby from F.R. Parts - He took care of my issue.
Good luck
