I've seen a lot of arguments over the years, here in the newgroup, and
the DVLA, or whatever they call themselves this week, might have changed
the rules again. But what I remember is a points system, with the
suspension being one item. the chassis another, and the engine a third.
And there's a limit to how many points-worth you can change.

Your big practical problem is the effect of full-time 4wd on a Series
front axle. Otherwise, you could just change engine and transmission,
and I don't think that breaks the limit.

I'm not sure what counts as a modification to the chassis. Since you can
change, at a points cost, suspension and engine, there might be a bit of
tolerance for changes to engine and suspension mounts.

Worst case, you end up with what they consider to be a Disco with a
Series III body, and then you use the cherished mark trick to transfer
the number plate.

Easiest way would be to transplant the least amount possible and then
declare it to the DVLA. Once they've said "Ok, it's a Series 3 with a
Disco engine" or whatever, keep swapping stuff.

Just try to keep photos and records of whatever you do, can save a lot
of hassle.
