TacoRunner did it in his 3rz powered 1st gen runner. I know its different then a 3rd gen but that is someone i know that did it.
He used the ENTIRE dash and the ENTIRE harness even the heater core and everything. He had to redo all the stuff for the heater core cuase its in a different positon but I dont know what youre going for. If youre going for just swapping it then it may be no big deal but if you do it like TacoRunner did then you gotta do a lot...
When he got done with it though it looked reallllllllly nice.
