I have never seen one available separately, but Joe Lucia will have the definitive information on it.
Just to throw some stuff in the pot
I have seen early HEI equipped Corvettes with date codes burned into the ring and/or distributor cap. Since cars this new are not my forte I expect there are others who can contribute more definite information than I can. My only point is that there may be more to this area than just the proper ring.

Three possibilities, most likely 12020635, alternate 1202620 third 12004716. Differences are the location of #1. I'm using the AIM to id the likely correct part based on the wire locations..Bill Clupper #618Comment

All------
Well, I've spent about an hour trying to research this one. The only reason I did was because I hate to get stumped trying to come up with a number, but I found the whole thing to be pretty vexing.
The best I can come up with is one of the numbers that Bill also mentioned------- GM #12004716. According to GM this piece was last used for 1984 Corvettes, but I suspect it was used after that, too. Unfortunately, it's GM-discontinued.In Appreciation of John HinckleyComment

I have a 84 to 87 parts book that I got from a Chevrolet dealer back in the 80s and what I find is that that part is called a cap cover and it is an 84 part but used on a 86 also and part # 1875960.Comment

Joe
In the parts book the cap is listed as part #1977046 group 2.367 and the cap cover is listed as part #187560 group 2.368 they are not shown in the green pages diagram which does show the distributor but the cover is not shown in the picture. Since these parts have been discontinued the only hope is a swap meet or the bone yard. It is getting hard to find parts for these C-4 but there are still some good ones around.Comment

Re: Distributor Cap wire ring?
Peter as William has suggested going to a bone yard and also look at different GM models. You must be careful they maybe be V8 rings but the alignment of the firing order and the 2 retaining clips are not. When we had my wife's 85 one of the retaining clips had broken off. Finding a correct ring took 4 years GM had discontinued it did a swap meet and bone yard check. Bought the first one I found but the alignment was not correct. I did find one at a swap meet.

Re: Distributor Cap wire ring?
That is true, the differences in the part numbers I gave in my response is the location of the numbers molded into the ring to designate the location of the wires for the firing order. The rings themselves are interchangable as long as you get the individual sparkplug wires in correct firing order for your car, regardless of the numbers molded on the ring.Bill Clupper #618Comment

Re: Distributor Cap wire ring?
Okay, the best I can discern is as follows:
12004716 - available in limited supply for about $9 + shipping. It appears that 12004716 is the correct part. Here is a photo of it. (click photo to enlarge) Does this look correct to you guys?
12020635 - does not appear to be a valid part # & if it is, its not available
1202620 - does not appear to be a valid part # & if it is, its not available
1875960 - this is not the wire ring; it is the coil cover cap. Here is a photo of it. (click photo to enlarge) CAP-DISTRIBUTOR - Part Replaced by: 1875960X - available for $6.15 + shipping
