I modified my bellows to have the contacts of an A lens.  It worked ok,
but I had problems actually mounting the camera.  I ended up buying a
12mm extension tube with A contacts and modifying that so it looks like
an A lens on whatever I attach it to.

With the bellows you have to set the f stop on the camera to the
maximum you can.  Using a double shutter release and a box that
triggers the cameras electronically I get perfect P-TTL exposures.
