I strongly recommend upgrading to aftermarket pushrods for the tailfeathers. My experience has been that they don't slide that smoothly. Also on a hot day you will need to make trim changes because they expand (lengthen) as temp increases. I used the stock outer tubes with 2-56 metal rods sliding inside (threaded at the tailfeathers for adjustment).
I concur. I did the same thing 2-56 rods into the stock outer tubes and also bought dubro metal clevis's.
