I will contact someone tomorrow to figure this out...

you need to know about your diffs ? right is there something else you wanna know.

you have a 2002 hilux with a 2.5 diesel

Yes, Bazzi, thats correct. I would appreciate that!
My main concern if differentials: I know rear is 8" with 3.91 and LSD, front is 7.5" open and... what? Are those front axle shafts 1.1" or 1.3"? I'm looking for TrueTac aplication to front and there is 2 options, 911A342 or 911A445, witch one fits?
Rear should be 913A610, but i would be happy if someone could verify that too...

I 'm planning to regear too, but not sure yet if i do Marlin dualcase (<-if it fits??) or just axle gears.
