Rallye Speaker Fader Switch - R11 AM Radio 1 Front 1 Rear Speaker

[70_440-6Cuda]

Anyone have a photo or details of the correct fader switch for a '70 'Cuda with a rallye dash, R11 2W AM only radio and 1 front, 1 rear speaker?  Trying to determine what exactly I need and want to make sure if I find one it is for the right application.  Thanks

A single rear speaker ? That's odd

A single rear speaker ? That's odd 

R11 with R31 is AM and single rear speaker
R22 AM with tape or R25  AM/FM with R31 is dual rear speaker

You're looking for a single pot fader switch.
Here is the dual pot version which you don't want.

Can't take credit for it. Great thread in the resources section in the radio configurations.

Read here and download pictures for fader hole location measurements.

Rallye and non Rallye dash have different locations.

Also there is a different bezel for Rallye dashes. They both take the same knob. knob and rallye bezel available here repro: http://www.n96airgrabber.com/products.asp?cat=11

Cool guess I've never come across that combo before....learned something new today

[Slotts]

Mono rear fader potentiometer- PN 2947444
Stereo rear fader potentiometer PN 2947672
Both have a metal tab to clock the fader pot into position on the face plate. Original factory heater control plates using a rear fader had three holes. A 29/64" center hole plus two # drill 26 holes at 12:00 and 3:00 positions that are offset from the center point by 7/16".
The mono tab uses the 3:00 position hole and the stereo tab uses the 12:00 position hole.

@Slotts that is exactly what I was looking for, thank you!  My car came factory with the R11 radio with 1 front and 1 rear speaker and rallye dash - was just needing a visual of the back of the fader switch so I know what to find - thanks all!
