Our gearbox has gone on our 95 WRX, the code was TY752VB3FA. We have been offered a box with code TY752VBAAA (same gear ratios but different rear diff type). Our diff code is C (Screw refuse type LSD - 27011AA280) and the other box is F,G (Sure truck mounted LSD). We haven't removed our rear diff, does anyone know if this will make a difference if we buy this box and fit it as it is, or will the rear diff need replacing with the other type?
Thanks for any help!

as long as the diff ratio is the same as the box you should be fine.

 

Be slightly carefull
Make sure the drop gears are the same. Some are 1:1 (Jap boxes) and some are 1:1.1 usually UK boxes.
This has an effect on the ratio of the rear diff to the front.
