driving me nuts

[tenggo]

hi there, i need help with which auto to put into my vr 19/9/1994. it is 450kms away from home and the auto is gone so the guys out there are trying to id it for me. the only markings on it are m30, it also has a raised m23 somewhere on it. with the pins the female has 20 holes and the male is in a position where it cant be seen. there is no sticker with either 4 or 5 hdd aywhere to be seen.

can anyone tell me which one it is as i need to buy one today and drive out there to replace it, but being so far away i really want to take the correct one, thanks
