Well, you kind of threw away the baby with the bath water.  There is no 
need replace the area where the newer fusebox mounts.   The area is 
already properly shaped for the newer fuse box.  All you need to do is 
cut the hole for the housing and seal it with butyl tape (same stuff 
used by the factory).  It will be indistinguishable from the later fuse 
box setup.  You will want to remove the old fusebox bracket, and weld in 
the two brackets for the relay panel, but that is all you need.  You 
should have saved the wiring and forgotten about the sheetmetal.  You 
will want CGT wiring for the rear harness(es if you have a rear wiper), 
as well as the control stalks, but 4kq harnesses will work for the 
rest.  Either way, you will have to make some changes, especially in the 
lighting circuits, A/C, starter and battery no matter what you do.

As for the RS2 harness, yes, that will work much better than the S4/S6 
AAN harness.  I'm not sure where Martin gets his 99% from, but I have an 
RS2 harness, and while the black connector with five wires that goes to 
the fuse box has them in the right places, and the fuses are easy to 
connect, but the other 19 are not plug-in compatible.
