Dude I have the same problem in my 92 GSR. I am told that this is the first thing to go wrong with Honda transmissions. Mine isn't a terrible grind yet, but it is pretty noticeable. I'm going to get my tranny rebuilt eventually, but for now I am just going to stick with what I got. You should be able to get around fine for a WHILE if it's just third and not too bad of a grind. You may want to buy a tranny from a junkyard teg or something, but it's a gamble: Could have the same problem... Good luck to you!
