The  Corvair rear suspension is designed to have some 
compliance  provided  by the four rubber bushings. Nylon ones have no 
compliance and 
will   eventually cause a failure.

I'm not sure the situation is quite that "dire".  I have seen years of  use 
on the Nylon units. But I do not recommend Nylon at the outside end - either  
end, for that matter. The newly available poured Urethane - available in a  
couple of different hardnesses - are much better for the street, and the Heim  
joints, like Andy is running, are great "for racing only". Some have used Nylon  
on the inner pivot and rubber on the outside, that helps withstand the  
inevitable deterioration of the inner rubber by oil. (Please, no letters) but  the 
Urethane solves both issues and leaves some needed compliance. If you are  
running the hard nulon in the front bushing of the trailing arm, you will likely  
need no stabilizer arms at all. The nylon should positively locate as a  
pivot (for better or worse) the trailing arm.  Also, if you run full  nylon on the 
rear, make sure your dental insurance is paid up!  - Seth  Emerson
