GSR Tranny

I have a 90 integra ls and I think I messed up my synchros since it grinds in second and third gear when I'm pushing it but not on normal driving. Therefore, I thought that it would be a good idea just to buy a new tranny. From what I hear, the GSR tranny is supposed to be stronger than mine now but my question is would it fit my engine???

yes but finding a cable gsr tranny or any short ratio B tranny is like finding a needle in haystack now I just converted a hyrdo myself lol.
