I got a new to me trailer and want to replace a few things.  There is a light on the inside of the trailer that lights up, but it does not have a cover on the light.  I have tried tractor supply, wal-mart, lowes, home depot, cargo trailer supply companies for just the cover and no one has them or is any help.  Where could I get just the "lense" in the OKC metro area?

There are also hooks on the outside of the trailer to tie the horses to while you saddle them and a couple of them are broken and I can not seem to find them anywhere either.  Any ideas?

I am also going to purchase new tires for the trailer, it is a Thuro-Bilt Spirit model, 2004, we pull it with a 2008 F-150.  What kind of tires do you recommend for the trailer? 

Thanks for any help!!
