Yep, they are identical! just get yourself a 22r or 22re 4x4 oil pan and pickup tube!  I had that same problem with a 20r celica engine in my 84 reg cab.... my axle was moved way forward and I only had push pull..... climbing my oil would all run to the back of the pan and starve for oil.... it was gay

whats with puttin celicas in the pickups!!?        thats nuts, but she runs like a raped ape so i cant complain i suppose!  
starving for oil is pretty gay!       good to know that i'm not the only one that has a celica race engine in his truck man! ha ha
