Any thoughts on My Trucks Value and how to b horse trailer worthy?

What is my 64 Chevy S10 worth?  Runs good just needs new steering column. Fairly rough body some rust needs new wood in Bed. Needs nicer seats Do u think I might get 3000 for it? I actually would like to keep it if I could fix it to where I could pull 2 horses in my 3 horse slant stock trailer(aluminum ) safely. Any thoughts?  I have had people tell me it is an easy truck to work on & that I could depend on it more than my 2001 Chevy Silverado that does terrible on roads when it rained. Spent 1400 to get it running where a few people told me most places would have charged 3000. I want to take both my Chevys so I can get something to take my horses places safely. Any ideas?
