Personally, I think that I would make up the cable as shown, but without 
all of the metal hardware around it.  In other words, an 8-conductor cable 
with a PL-152 or 152-A on one end and an 8-pin plug to mate with the connector 
on the rear of the receiver on the other.  Assembly time the same as that to 
make up a dual PL-152-(*) cable.  If you use a modified rack, you can't get 
at anything much on the bottom of the receiver.
