... you can find a 280 in a yard? it's likely the rarest vehicle in the mercedes lineup...
I've seen a few but not many...

even so... if you find one, best to bring the entire car over for the swap, then you'd need nothing else for the build.
I suppose you are planning to do away with the rear suspension?
