Wayne,
I don't know if this will be of any help, but it is worth a try. I had a ctc5 Special with a bad crt, I sold it to a fellow by the name of Ed Milbourn in Indiana. He wanted my set as a source of parts to restore another CTC5 that he was working on. Ed may have the parts you are looking for and may be willing to sell you what you need.
Tell him Bob Galanter in Milwaukee who sold him the ctc5 gave you the referal. Ed is a real nice guy and I would think if he has what you need he would be happy to sell you the parts.
BTW, Ed is looking for a 21axp22 that he can use in the restoration he is working on. I think he may even be open to one that is weak but undervacuum and can be rebuilt. If anyone can help Ed on the crt issue, please contact him.
Ed's email address is:
