No it wont fit actually. The crossmember is the wrong way around to fit the v6. There is a way around this though and it requires some really radical engineering and a donor car.
The front crossmember has to be reversed so the bend now faces forward and the engine slots in .
But this also means that the king pins are now facing forward. To get around this,the rack and pinion steering from the donor car will now work fine but a shaft with universal joints must connected to the steering column. The two flat spring mounts now need a new mounting point so a donor front axle will need to be sacrificed. Cut off the mounts and weld them to the opposite of the mount points on the axle . The existing ones can be used to provide a positive stop with short links back to the chassis rails. This will improve handling and braking.
I dont know about the UK,but here in OZ there are plenty of derelict finnys and W108's laying about so getting a front axle to chop up is no big deal. You will also need to upgrade the front brakes to W108 or W109 V8 vented units ,plus swap the diff to a V8 version (280 SE 3.5 or 4.5) to get a higher ratio and four wheel discs.
Will Holman in the UK got around this by simply fitting a W126 560SEL rear end .complete under his car,and i am sure there is a coupe in the UK with the same Idea fitted.
If i were to go to the V6 engine i would be looking for a AMG supercharged version and use as much of the cars engine wiring etc as possible . You need the speedo,key ECU trans etc etc to make all this work but it is a good conversion when done. Yes it has been done...but required hell of a lot work to get it running. No pics sorry.
