I believe that the turbos from virtually any Chrysler product are the same. You are ideally looking for a .42/.48 turbo, and it will be written right into the casting. They are available in mini-vans, new yorkers, daytonas, lebarons, and even some k-cars.
I used a 13B-T manifold bought from G&S. It bolts right up. One other option is to build one. Lowenbrau on this list made on using two 1 1/2" 90's and two 1 1/2" tees welded to a plate which matched the bolt pattern. He then cut a hole and built a mount for the turbo on top of the pipe. Lots of fabrication involved. Lastly, another option is to simply flip up your 3B manifold. It is the least graceful, but it still works.
HTH,
