[TowerTalk] Emergency Rohn 45 foldover help needed!

Hi,

I have a Rohn 45 foldover I was hoping to erect this saturday - I have 
a bunch of people coming over to help.  Unfortunately, as I walked 
through the pieces today, I found a large problem - the fold over 
assembly does not match the engineering diagram I have!  My diagram is 
from 1981.

I must have an older model.

The arm terminates in a bracket which has two holes:

------------------------------------
                                      |         |
----------------------------|         |
                                      |         |
                                      |   O   |
                                      |         |
                                      |   O   |
                                      |____|

presumably one is for a bolt/thimble to attach to the winch  and one is 
to attach, somehow, to the tower leg. But the exact details are unclear 
to me.

The diagram I have shows these two functions at different points on the 
fold over assembly - I don't have a corresponding point for the winch 
cable to attach.

I really really really need a copy of the engineering information for 
this tower ASAP that explains my arm - if I can't find it, I'm afraid 
it isn't going up saturday.  My fault for waiting to discover this.

The other big question is whether I should assemble this tower with:

27' below the hinge and 36' above (which is about what Rohn suggests) or
37' below the hinge and 27' above (which sounds safer to me - but i 
have a guy here vigorously arguing I need to follow Rohn's model)

I am guying this at the hinge and at the top.

Thanks for any advice/suggestions.
