Hi,
im about to change the diff oil, but i dont know where the filler hole is.
On the driver side of the diff, there is a hex shaped hole (ive tried this one, but it wont budge) and on the passenger side, theres 2 bolts that look the same (above the exhaust)
Also, ive noticed that there is a hose running from the diff into the boot. In the boot, there is a fluid reservior, i was wondering if thats the diff oil??
My car is a R33 GTS-T Series II
