Hi gbw,
I don't think that your 73 had the GM stamped hoses originally.
I believe they had various numbers of raised ribs in them and 2 letter codes stamped on them.

Typical ribs. Rowdy Rat's LS-6 restoration.

Red is not an option I would chose. Talked to Corvette. Central today. They say NCRS used to require white letters, but has changed to black ribbed. Therefore the put both as correct in mag. I am considering ordering black and sen white letter back when the black arrive.

The GM[] was typical on later C2 Corvettes... There was some carry over into 1968, but for the most part, that was it. Later cars used a two letter broadcast code in white that identifies the application and a series of grooves (not raised ribs) that denote the hose manufacturer.

That's pretty close.

You have a couple of options...
You can hunt salvage yards for old passenger cars and pickup trucks... They use the same hoses and while the broadcast codes will be different, nobody really has a handle on that yet (or the grooves for that matter) and the configuration is spot on. The downside of course is using 40+ year old heater hoses. That may be OK for a car that is never driven, but for most of us, it isn't practical.
Second option is to go with a good reproduction hose. You'll be missing the broadcast codes, but the configuration is really close and you won't be worrying about when that old hose is going to let go. I've used Dr. Rebuild for my heater hoses and have never had a problem during judging with them. Other suppliers may offer a suitable product, but I have no experience with them so I can't offer any other suggestions.

Heater Hose
Been awhile since on forum, but update: When I took the old hose off the 3/4 had 2 white strips and EBDM EB D09142 in white, the 1/2 had one white strip with 78E60 EBY 221 D12182 in white on it.
