John,

I left both sets of points in.  The only thing the MSD senses is the 
breaking of the current flow when the lead points open.  It doesn't 
matter if the trailing set is in or not.  Mine are in for now.

Distributor fits beautifully, no interferance.  The cap is about the same 
size, maybe a bit smaller.  I believe it sticks up from the block a bit 
less.  There's not much inside this case.  Oh, it has the new centrifugal 
advance mechanism developed from circle-track racing (more robust).

If you're interested I can get the part number for you. I forgot to write
it down.  I don't believe the part number is in any catalog yet.  Mallory
was very supportive.  They really wanted this to work.  Dave Forbes
(Mallory Cust Serv 702 882-6600) was very gratefull when I offered to ship
my old distributor.  You may want to contact him.  It would let him know
that we appreciate their help keeping the IH's alive.
