My copy of the '66 assembly manual does not have any separate "M20" 
accessory section.
It does show  p/n 3881738 for 10100-500 (500 and Monza) and 3872872 10700 
(Corsa)

There are two change notes:
(2) - was 3872872 lever changed 7/7/65
(5) - 3881738 lever was 10500-700 (Monza and Corsa)
         3872872 10700  lever was 3881738 - 10100 (500) changed 10-22-65

What this sounds like is that originally (April 21, 65) there was supposed 
to be just one shift lever 3872872.  On July 7, 65 there were two levers, 
3881738 for the 500 and 3872872 for the Monza and Corsa.  Then on October 
22, 65 the -738 was used on the Monza and Corsa and the -872 became Corsa only.

Note the use of p/n 3881728 (in note 5) and 3881738 in other places. I 
suspect this might be a typo

I do not know how long it would take for the change notices to reach the 
production lines but most likely the first one went into effect before 
production began and the second somewhere before the midpoint.

This appears on page 7-B2 (Clark 1966-103) of the 1966 assembly manual. One 
question comes to mind since the assembly manual does not seem to have 
installation of the seats (did I just miss it ?) would be whether a 
different shift lever was used for cars with the bench seat standard and 
whether there was a change in standard seats for the Monza during the 
production run.

Just to really confuse things, my '73 parts book shows the 3881738 for 
66-69 three speeds and the 3872872 for 66-69 four speeds

It is going to take a drawing of the lever with dimensions (or someone to 
measure a couple) to determine if there is a difference in throw but it 
sounds like the same lever could be used for either the three speed or the 
four speed.
