IH all,

My new '67 800 is in need of a basic tuneup and I'm facing the age-old
mystery of distributor caps again.  As most of you know, IH used two
different distributors on their 4 cylinder engines during this period: I'm
still not sure which is which.

Here's what I've observed so far:  the distributor on my '68 800 has a
clip-on type cap and small rotor.  I've been told that this is a 'Holley'
type distributor.  My '67 800 (again, the one that needs the tuneup) has a
cap held on by two screws (the rotor I haven't seen).  I believe this to
be the only other type of distributor used, which I believe to be a
'Delco' type.  All of this knowledge is through parts store hearsay and my
own observations.

[Note: Both my 800s have 4 cylinder engines.]

So, here's my question: does anyone know the *real* designations
(manufacturers) for these distributor types and (oh please oh please) part
numbers for a major chain in this area (Napa, Pep Boys, AutoZone,
Advance)?  I am dying to get this Scout back on the road in top running
condition and I don't have time to play "find and compare" with several
different chain stores.  TIA,
