If I understand your problem correctly, what happened is that the
distributar shaft w/ the gear and rotor on it has rotated from when it
was installed previously.  This means that in order to get the timing to
10 degrees BTDC, you need to have the housing (with the cap) rotated by
the same amount, and as you have noticed, this means that you have
clearance problems.

If you pull out the distributor, and then put it back in rotated one
groove on the gear in whichever way will give you more clearance, you
should be set.  You might have to use a screwdriver to rotate the oil
pump shaft (I assume the IH motors are like this...mostly I've worked on
chevys) so that it will slide down in there.  Then, just find TDC again
and use that to get your initial timing.  You'll find that when you get
to your 10 degree setting, the housing of the dist will be in the
correct spot.

I hope this makes sense,

Chris,

Thanks for the reply.  IH distributors are a bit different in that the shaft
ends in a flathead screwdriver tip with the gear fixed above it- so I don't
see how I could've screwed things up in terms of distributor installation (I
don't think, the scout didn't move when I had the distributor out).  So, I'm
thinking I could've screwed the internals up when I cleaned/regreased
them...
