Huw  nailed it(thanks Huw!), new oxs and cat installed last PM, mixture
is all  happy now. Now back to my original question, where is the 0 for
tdc  supposed to line up in the window for ignition timing? Just need  a
reference point to start from(who knows where it was from the  PO).
Also, is there an easy trick to get those "donut" seals at either  end
of the cat to seal tight?(mmm donuts....) Even with new hardware  and
new seals I've still got a small leak by the downpipe.

TIA  
Brendan

I take a wire wheel to the surfaces and donuts every time I have them  apart 
to get rid of surface irregularities and corrosion that would cause leaks.  
Seems to work for me.
