swapping a manual transmission into a 1992 svx

im using a 1992 2.2 legacy L wagon 5 speed manual transmission, anybody have any information like problems I may run into doing this?....I know the basic stuff, I have to use the same rear differential out of the same car the transmission came out of, and I know I have to probably modify some trans braces, have the driveline cut to fit etc, but any other situations......I have done a lot of online research and am learning a lot but if I was lucky enough to talk with someone who has already done this, that would be really great, thanks Randy
