[TowerTalk] Wilson TT-45 tower "swing" problem

[Gary Gross]

Hi
 This is Gary KE6QR in Vallejo, Ca. I have used a Wilson TT-45 tower tower for 28 years now. last year I lost my System 36 tribander and replaced it with a 3 element SteppIR with 6 meter passive element and 30-40 meter trombone. While I had the tower retracted I noticed that the flat bar that serves as a keyway which interlocks the inner and outer tower sections had several pop rivets "missing". I replaced the missing rivets as best as I could (except whatever rivets may be retracted where the two sections come together. 
 The problem is that whenever the wind is blowing, the upper 20 foot section torque's back and forth about 30 degrees, which never happened before. My question, is this a dangerous situation, and how does one get inside the top of the bottom section to find a repair solution? Incidentally, while the tower was retracted a friend climbed to the top on a ladder and was able to make it torque exactly the same as when it was extended. Also, where can I find a replacement for my winch cable? Thanks. Gary. ke6qr at comcast.net
