will this box go with this diff
 

i have a 95 diff and box with the code ty752vb3aa but the box is knackered so will a 93 wrx box fit the only difference is the code at the end being 3fa.

i have looked on the spda website and all the gearings are the same but have a different box number

As long as the final drive is the same then you should have no issues.
