[NSRCA-discussion] Ball bearing clevis'

[Ron Van Putte]

The bottom url is for two turnbuckles (DuBro 2157).  You can get the  
same two turnbuckles, with a wrench (DuBro 2156).  Of course,  
enterprising individuals (tightwads, like me) can buy the 4-40  
threaded rod, a reverse thread 4-40 die and make their own custom  
turnbuckles to the desired length.  The same is true for a 2-56  
version of the turnbuckle
