Topic: AM radio reverb unit

[mikelj5S230]

I am wondering if the '64 1/2 had an option for the reverb unit and the package shelf speaker, or was that aftermarket or not available on '64 1/2s?  Thanks.

Short answer ; No, not as a Factory Option, but Yesm as a Genuine Ford Accessory that could be purchased at a Dealer's Parts Department.

Ford actually called its Reverberation System (which was actually made by Motorola) the "Studiosonic Sound System". Ford first offered this in 1962 (Part Number C2OZ-18875-C) for $22.95. In 1964, Ford replaced the 1962 version with a C4AZ-18875-A Kit (both Kits were shown for all Models, except for Convertibles), which now had an added Foot Operated Switch (identical to a headlight Dimmer Switch). A picture is attached from the 1964 Ford Accessory Brochure, I don't know the List Price of the 1964 Kit, as I do not have a 1964 Price Book, and the 1965 Price Book only shows the Part Number, as by then, the C4AZ Kit had been Replaced by the 1965 Kits. In 1965, Ford Replaced the C4AZ Kit with a C5AZ-18875-E Kit (shown for all Models, including Mustangs), and a C5ZZ-18875-A Kit, shown specifically for Mustangs. My guess is that the C5ZZ Kit had a wiring harness specifically tailored for Mustangs. Also of note for 1965, is that the Foot Operated Switch to turn the Rear Speaker On/Off, was now shown as an option for $3.75.

In 1966, the C5AZ and C5ZZ Kits were replaced by a C6AZ kit, which was forall Models, including Mustangs. There was no longer a  specific Kit for Mustangs.
1967 again saw a change in Part Numbers to a C7AZ prefix, but now because of a change in type of unit. Prior to 1967, all reverberation units were mechanical, relying on springs to produce the reverberation effect. Beginning in 1967, the reverberation effect was done electronically, aqllowing for a much smaller unit.

For more information, you ma6 want to see my Article in the "Library" Secion.

Hope this helps,

Thanks very much, I don't see any Ford part numbers on the amp under the package deck, but it has a sticker saying it was made by Gibbs Manufacturing and Research Corp. in Wisconsin.

That would not be an original Ford Accessory. As I noted, 1962-66 Units were made by Motorola.

Thank you!

I see the same question was asked on the FB page under a different context.  The FB question was focused on a judging deduction being made for having the accessory option present.  I made a comment but it would be interesting to see what the experts say and if it varies by judging class. 

Sometimes a vague question will get a vague answer.

In a MCA show typically the standard has been that if an option was available at the time of sale and you document that along with the Rotunda or Ford part number (helps to have the ad too) then there isn't a deduction if everything is installed as it should be with some variation since these were done at the dealership often by the low man.  At the same time if an owner chooses to add a bunch of this sort of options there was language that allowed for deduction for over accessorizing or similar wording. In some cases in the past owners have focused more on loading on the options rather than letting the car be the star

The reason I didn't ask about the deduction here is that over the years when I have done it here, it did not seem to be welcome, and technical questions seemed to be the norm here. The FB page seemed much more friendly about asking about deductions. However, I thought I asked very specific questions here and on the FB page, sorry if they were not clear.

We try to focus on correctness here, not necessarily correctness based off of judging standards.  Discussions about judging and points can be posted in the MCA/SAAC.. specific sections.

Thank you Charles, you have been very helpful to me in this process.

OK, I now have looked more closely at the unit, and it has a number stamped on the back that is 15B64670A02 which coincides with the C5AZ-18875-E kit part number I see. So I am now thinking this is an original type one.  Thanks!
