200tdi radiator, confused

I have a defender 90 which is converted to a 200tdi, the radiator has blown and I need to order a replacement quick!

I am told there are 3 different ones and not sure which I need!

Problem is I'm away from home so can't stick my head under the bonnet.

Probably been asked before, but what are the differences?
I think it's the position of the inlet and outlet, but I guess it may be more, any ideas?

I don't have the year of the vehicle that the replacement engine came out of.

Any help please,I'm a bit desperate

Steve

Is it a defender engine or disco engine ?

Came very quickly. I just removed the oil unions, put PTFE on my old ones and tightened them in. No dramas. Can't comment on the longlevity of it though as I've only had it a week!
