Hi,
 which Yaesu one did you get? I'm going to guess the GS-050, I wanted a TB-25 sometime back
and they were not available then either, but I found the the bigger Yaesu GS-065 was a match for the TB-25
bolt pattern…  this was on a RT-832 btw but if a TB-25 was suppose to work on a RT-936 then the GS-065
should fit.

When I purchased my US Tower, used, a number of years ago, whatever  
had been used to lube the rails was sticky and gummy. The tower would  
actually stick and grab while going up and down. I called US Tower  
and was told to clean off the old lube which was used during  
manufacturing and to spray the rails with "Slip Plate". You can buy  
it at any hardware store. It comes in a spray can and is a graphite  
based paint, if I'm not mistaken. Tower works fine now and has for a  
number of years.
