Bruce,
The aftercoolers for the 4BTA mounted on top of the engine....water cooled.
I might know of an NOS one you can buy but to be honest...unless you plan to turn the power way up you just don't need it.
I'd install an intercooler up front if I was worried about it. Grab one out of a first gen & plumb it in or lots of guys costom make them.
The intercooler in my W500 visible in the picture was built by a company in KY for $600.
