hiya i have a 1995 subaru wrx and its crunching into fifth gearbox ive just changed oil to syntrax and still the same im now in need for a gearbox where is the location of what type gearbox i need as i seen on ebay that there is different numbers for the box cheers in advance for any help

 

i have found the geabox code and its ty752vb3fa and was wondering will all the wrx gearboxes fit and is this just a code for different gear ratio and what would be the diff by putting a different code gearbox in thanks
