[TowerTalk] WTB HBU or HBUTVRO Bracket(s)

[rentwist at comcast.net]

First,

Thanks to everyone who responded to my query regarding my proposed tower installation.  The jist of it is don't put up 55 feet unless I guy it.  Maybe 45 feet with a bracket at 21 feet, and then use two brackets.

Now, about brackets (and being more direct in my inquiry).  I would like to purchase a HBUTVRO (preferred) and/or HBU bracket, new or used.  Please state price and condition.  The HBA/B/C series of brackets look a lot weaker than the HBU ones and thus my preference.  

Also, am I correct that the HBU and HBUTVRO brackets are adjustable (extra holes) for 25G, 45G and 55G??

Alternatively, I am considering making my own (especially if I use guys, makes the bracket secondary rather than primary means of support).  Does anyone have or know of design/construction information for these (or similar) brackets?  I could devise one of my own using the isometric drawings in the Rohn accessories PDF as a starting point, but it will be a WAG to some degree.

I assume that soft steel angle is the way to go and not tempered steel (like that found in old bed frames).  The tempered steel is very strong, but brittle.
