Changing of body shell

Need info regarding the changing from a Disco 1 to a Disco 2 body shell. Will the chasis be compatible and if it needs modifications, what are the stuff that I need to do? Any difficulties involved. Is it possible? Please help. Need to do it badly.
Thanks a lot. Cheers!

i wouldnt bother, the chassis is totally different.

Not saying it cant be done but there will be loads of mods to do, not done it myself so cant tell you what would need changing/modifing. cant see that there would be many people out there who have done it.

up to you, dive in there and see for yourself or just go buy a Sll
