Auto Parts: 4x4 hub parts, hubs, bad idea

Question
I have a 1971 3/4 ton chevy. The hubs are spisers. I busted the plastic peace that you turn to ingage and disingage the hubs. I can't find any one that sells just this peace. Do you have any ideas where i can buy just parts. Everyone around here wants to sell me the whole hub. Thank you for your time.

Answer
    You're not going to find that piece anywhere, I think.  But, since the hubs are just shy of forty years old, new hubs would not be a bad idea.  I would go with Warn™ hubs; I sold them for a long time and they are good quality at a very reasonable price.  Of course, shopping around wouldn't hurt, pricewise.
