Will they fit ?

[rookierodbuilder]

I was wondering if 73-87 chevy ball joints will fit into the a-arms of my 66 c-10. The reason that I ask is because I am doing a budget disc brake conversion and I know that the ball joints are different, but I do not know what dimensions are different about them. Is it just where they mount up to the spindle that the difference lies, or is it where they fit on the a-arms. Please help so I know what ball joints to buy.

thanks.
