H31 Masthead

I am installing a wind instrument on my 1986 H31 masthead. I have not had a chance lately to go visit the boat to have a good look. The mast is down but when layed out on some stands on the deck it is still about 15 feet off the ground. So until I have a chance to get a tall ladder and brave the winter winds off the Straits of Mackinac, I am hoping someone has done this and can give me a bit of advice.
The (fuzzy) photo I took makes it look like the light is too close to the front of the mast for the mounting bracket.
Can the light be moved back?
Is there easy access to the wire conduit at the top? I am thinking that it may be a good idea to replace the 30 year old light wire, which would mean I could use the old wire to pull the new and the instrument cable down the conduit.
I think it is an Isomat mast, but does anyone know which one?

Short answer is yes, the light can be moved and relocated to accommodate wind instrument. Attached are pics of the top of the mast where i moved an old light and installed a new LED. unfortunately don't have pics of the mast with my wind instrument attached. also attached pics of the bottom of mast showing conduit areas. hope these help.

Perfect. That gives me a much better idea what to expect when I get up there.
Except for the mast holding up my tarp, those pictures make me wish I had put the mast lower to the ground. Having to do this at the top of a ladder will be interesting.

Maybe a set of rolling steps? Would provide a better work platform.

It looks like I will have to add a mounting plate. The light and wind sensor mount will not fit together.
