Does anyone have pics of their safety wiring the tension arm bolts? The distance between them seems a bit much to tie one to the other.

Ran into the same issue a few months back. Just drill some small holes into the tension arm and run the safety wire from the bolt to the hole and tie it off.

While it may be "okay" to drill a hole, there is no need to. You can easily safety directly to the arm. That is done all the time on certified aircraft.

I re-read AC43.13 and didn't find any mention of a limit to the length of safety wire that can be used. I simply brought the wire from bolt to bolt in a typical arrangement and the span looks to be about 3". Is this a problem? Seems ok to me.

There's no doubt that shorter is better. The longer the span the
'potential' for loosening becomes greater.
So, ask yourself what the consequences of that (those) particular
fasteners loosening a little.
This could be an 'experiment' so get back to us ......
IMHO, of course.

I suspect, in my experiment, I'll get a "backup alternator" light illumination on my panel. I'll then fly on or land...and adjust the belt tension when back on the ground. I'll then recall this thread, enjoy a good chuckle... and press on. 
Or... I'll re-safety it now prior to first flight. Haha.
