Anyone here know this 56 Coronet Lancer?

I was able to run to the shop for a minute tonight. I found this label on the driveshaft. I looked up the area and found a Mopar shop but he said he didn’t even know anyone in the are that worked on cars that old… Anyone know of any hotrod type shops that would have been in business 25ish years ago in the Slidell, LA area??
