We are going to attempt to
cover some history on this extra cost option with details
on some parts that are model specific and other parts are
interchangeable.
For this article, the focus
will be from 1968 & up into at least 1976.
The sales code for Auto Pilot
from 1966 through 1968 is 473. For 1968 through at least
1980 the sales code for Speed Control is N88.
This option was available on
B, C & E-bodies & some newer body types also.
It was also possible for any
dealership to add Speed Control to a car if the client requested
it & of course was willing to pay for it.
You can also source the original
used & / or NOS parts to add them yourself, more on that
later...
Just for fun, let's open up
a vintage NOS kit part number 3769294 dated later in 1975
during the 1976 model year to see what parts were included.
(keep in mind that other parts were not included in this
kit like the turn signal stalk, wiring harness & speedometer
cables)
As you can see, the label mentions
the servo, but there are many more parts inside:
Inside the box was this secondary
small parts envelope with part number 3837761 that had come
open over the years & spilled its contents into the
main box:
Here is a view of all the parts
inside. From top left to right & top to bottom are the servo,
servo to inner fender mounting bracket, the various mounting
nuts, two hose clamps for the vacuum line, a single wire
tie, the lost motion link to attach the servo control cable
to the carburetor, the special brake light switch with dual
blue leads.
Then in the bottom row we have
the accessory cable clamps needed for small block applications
(green) & the one for big block applications (zinc)
these are servo cable guide brackets:
Lets go over the date codes seen above, we'll start with
the box label. It was packaged on October 22, 1975:
The internal parts envelope was
packaged on the 117th day of 1975:
The servo assembly was completed
on the 295th day of 1975:
