aramasa has a skyline 250gtm if i'm not mistaken. last time i checked the dash kit for the standard din was only for this model skyline. i don't know why it wouldn't fit, but i suspect it's because those don't have the steering wheel mounted audio controls maybe? i wouldn't mind losing that one bit if i could get a good quality aftermarket deck in there though. i've had it with this pos stock deck. if anyone can get this from japan, i would be willing to pay you to get it for me...
