Hello Harold,
I would like to provide some helpful information for you regarding the dash mounted clocks that were optional on our 1966 and 1967 Coronets. Having the correct information on the parts that you will need before you start shopping is the best way that I know to avoid purchasing incorrect parts. If you end up having a used clock refurbished, or converting a used clock to a quartz movement and other modern related parts, knowing what the factory offered will also be very helpful to both you and the company that performs the work for you.
The following three pages that I've posted below are from my 1966 factory parts book that I've deleted non clock related information from to make it easier for you to read.
Please forgive me if you are a pro at reading information from the Chrysler parts books, but since we haven't had any personal conversations yet, I'll include some basic meanings for some of the codes that Chrysler used for all of the various car line designations. This might also be useful for anyone else that reads this thread.
Car Line And Model Designation Codes:
V = all Plymouth Valiant and Barracuda models (including Valiant V-100, V-200, Signet and all Barracuda models)
L = all Dodge Dart models (including Dart, Dart 270 and Dart GT models)
R = all Plymouth Belvedere and Satellite models (including Belvedere I, Belvedere II and Satellite models)
W = all Dodge Coronet models (including Coronet, Coronet Deluxe, Coronet 440 and Coronet 500 models)
W, WP, Charger = Charger models are referred to as W, WP, or Charger in the 1966 factory parts book
P = all Plymouth models (including Fury I, Fury II, Fury III and Sport Fury)
D = all Dodge models (including Polara, Monaco and Monaco 500)
C = all Chrysler models (including Newport, Chrysler 300 and New Yorker models)
Y = all Imperial models (including Imperial Crown and Imperial Le Baron models)
In 1966, Chrysler used five different dash mounted clock packages for their various Dodge, Plymouth, Chrysler and Imperial models and they used six different clock packages in 1967, but since you need one for your 1966 Coronet, I will only concentrate on the one specific clock and it's related parts that was used on all of the 1966 and 1967 Coronet models. This Coronet clock is model specific and will
NOT interchange with any of the other 1966, or 1967 clock packages.
1966 and 1967 factory part #: 2661816
1966 and 1967 factory parts book section #: 1-21-1
Part description: Clock package, W, (except Charger)
Applications: All 1966 and 1967 Coronet models, regardless of trim level, or body style that came from the factory with an instrument cluster mounted clock as an extra cost option.
All 1966 and 1967 Coronet models that did
not come with the optional clock package were equipped with the following part to cover the hole in the instrument cluster for the clock.
1966 and 1967 factory part #: 2631122
1966 and 1967 factory parts book section #: 23-33-20
Part description: Cover, instrument panel (cluster) clock hole, W, (except Charger)
Applications: All 1966 and 1967 Coronet models, regardless of trim level, or body style that did
not come with an optional dash mounted clock from the factory.
If an owner wanted to add a factory style clock package to their 1966 or 1967 Coronet after the car had already been built, they could have gone into any Dodge dealerships parts department and purchased the following clock packages over the counter and had it installed at the dealership, or by anyone else. I personally have one of these n.o.s. clock packages and will be installing it into my 1966 Coronet 500's dash cluster.
Factory part #: 2661816
1966 factory parts book section #: 1-21-1 under "Parts Packages", page number PK-1

1 cable, ammeter to clock (part #2770208
1 clock (part #2631120)
1 knob, clock reset (part #2631166)
1 nut, clock reset knob mounting (part #2257804)
Applications: All 1966 (and 1967) Coronet models, regardless of trim level, or body style that did not come with an optional dash mounted clock from the factory.
I will check some of my n.o.s. parts sources to see if any of them might have one of these clocks and will post that information for you if I find any leads for you ok?
