Okay, now I've got to remember the trick.  It involved tapping and putting 
a helicoil in a through hole in the late backing plate so that one of the 
early starter mounting bolts actually screws into the backing plate instead 
of the bolt going _through_ and being held in by a nut.  What I can't 
remember is _which_ through hole gets mutilated for this purpose.  We agree 
on changing to a new backing plate.  I kept the original backing plate to 
my car as part of the "stuff to return the car to original" parts stash.

I heard all those horror stories about bashing out the tunnel or grinding 
off the newer starter flange (since I'm not using it, it hangs out in space)
or cutting out the original tunnel and welding in a different one, but I 
didn't do any of these.  I did this conversion in two inches of mud in 
someone else's back yard when I had to drive the car to a final the next day 
and I wasn't too worried about noises, but I've never had a problem.  The 
only time it's hit is when my car ran on after filling up with Arco gas.  
Since I've never done that again, it's never clunked again.

I knew this was true of the 3-main vs. 5-main engines, but I didn't realize 
they did this later.  Thanks, I'll watch out.

Along the same lines, did 3-main B's ever come with overdrive?  I have an 
early OD tranny in the garage that's going in the car that currently has 
a late non-overdrive tranny in it and I suddenly had the horrible thought 
that it might be a 3-main OD tranny and then the input shaft would be too
