we are looking for dividers and drop down windows for our trailer and I haven't had much luck finding what we need.  I must not be looking in the right places.   suggestions?

 Maybe on Ebay? 

Do a google search for used horse trailer parts and you get numerous links.

Manufacturer? Model? Steel or aluminum? ~FH

Is there a trailer dealer near you?  The one near me can pretty much customize any trailer.  Or if you know a welder, you can work with him to put together something that will work. 

But FH's question is very important.  It's hard to tell you where to look without knowing something about the trailer.

I am still searching........ but the 'welder, customizer and general construction guy' is my husband.  (he's a very talented guy.)  He does all that stuff..  We were mostly looking for some good drop-down windows and grids and I think I found those.   We want to get the conversion done before we begin the new house and my husband is almost done with our house plans.  Thank goodness he is retired now or we would never get done.

I have been researching the things we need to do to make it 'horse safe'.  I found some great articles and info on one of the other horse sites.  I plan to take pictures of the transformation of the trailer. ...  Thanks guys..

Is this a home made horse trailer you are making or converting an old horse trailer with no windows or dividers and putting windows and dividers in?

It is not a horse trailer.  It's a utility trailer we plan to beef up to make strong enough for the horses and then add a sm. saddle room and to carry two horses.. we will be adding windows and some kind of divider and matting of course. 

aluminum says the husband.
