Does discovery radiator/cooling pack fit a defender

Hi guys, I've not been in here for many years, I thought my defender times were over for good when I sold up but apparently not
I ended up getting a completely standard 1997 300tdi defender a couple of years ago. Long story short....the chassis on it was ok, not great but ok. I decided I would change out the chassis at some convenient time so I bought a chassis and put it to the side for future use....well, shortly after that my defender decided to go on fire, totally burnt out, fire brigade the full works. So the rebuild has had to happen sooner than expected and obviously a lot more extensive and expensive than planned but that's ok. The question is as the title says. I have access to a discovery and am hoping to get what I can off it. I took the cooling pack off it the other day and I can see right away that the cowling that goes round the viscose fan is a different shape but the rest looks kind of the same? I know I put one in a defender many years ago and I think I had to cut the mounts down a bit or something like that, can't really remember...any help much appreciated
