WTD: current W124 BEHR evaporators pics: no more dissimilar metals ?

The factory installed W124 BEHR evaporator used aluminum tubing with a copper manifold.

Supposedly, the two dissimilar metals had very different expansion coefficients, and when cycled frequently eventually failed at the junction between the aluminum and copper.

Supposedly, the current generation of W124 BEHR evaporators do NOT use dissimilar metals anymore, just like the aftermarket ACM (all aluminum), or the Proliance/Modine (all copper tubing and manifold but with aluminum fins (OK), but with supposedly a poor fit).

Can someone please post pics of the current W124 BEHR evaporator showing the tubing and manifold junction ?

Thanks,
:-) neil
