[TowerTalk] Portable Mast Guy Rings?

[Brad Pioveson W9FX]

Hi, Guys...

Sorry if this is a stretch of the topic, but, it is an antenna support, so, 
with apologies, here goes:

    I now have 3 of the surplus military masts - tubular, aluminum or 
fiberglas sections that stack and were intended for use as supports for mil 
portable antenna systems.  None of the three units I have came with any guy 
rings.  Yep, I know that there are vendors that sell guy rings. 
www.tmastco.com is one such vendor.  He wants $7.50 a pop for his guy rings. 
If I can't find a local vendor, I suppose I'll cough up the $$ for the 
tmastco parts, but I think they can be had for less - the operative word in 
that sentence being 'think.'

    The thing is, I remember seeing, somewhere,  mentioned on a reflector 
that the items being sold as military mast guy rings are actually tractor 
parts...but, for the life of me, I can't remember what they were called at 
the tractor supply store.

    So...can anybody tell me what to ask for at Rural King or Tractor 
Supply?
