O.k. guys, I need a little terminology lesson today.
what is the proper term for these?

to be more precise, the black bushing looking things that the studs which hold the sprocket into place. I have noticed I need to replace my sprocket yet again as it is not seating the chain correctly, and I want to replace the studs as well. trouble is the home mode studs I created I had to drill the centers of these "bushings" out to get them to fit. Now I know that the new replacements studs will be smaller, and I would like to replace these "bushings". I also noticed they are a bit cracked and dry rotted so to speak. I have no idea the proper name for them to hunt them down.
Also I know there was a post a while back with the correct studs info, I cannot seem to find it. I believe they are Honda studs, which worked.
Thirdly, and I know I am asking a lot, but I do not like the sprocket problem. I need to purchase a new one, but I am not going with the same place I went with before, old bike barn. I do not know why the chain would not seat correctly, but I do not want to take a chance on the same problem happening again, so a lead on an alternate place of purchase would be cool.
Bike is up to 9975 miles at this time, but sitting in the garage without a sprocket has me buggin a little. I want to hit that 10,000 mile mark as soon as possible. Thanks.
