The two chassis are not the same size, and share no common parts. What we
are seeing is a "family resemblance".
As another example, I noticed the other day that a particular Ford
automobile seemed to have the same general nose shape as an F150 truck,
although there would be no common body parts between the two vehicles

That's funny, because I was under impression that *ist and *istD have something in common by development. This does not necessary has to be common chassis, but I thought that they are closer to one another than just two "family resemblant" members...
But I suppose here is where my mileage varied...
