Sounds like you have a really nice car with lots of options!

The housings for rear speaker with rear defog are available reproduction from Mike at BE&A restoration parts. I haven't seen the reproduction piece in person because I have an original, but usually his stuff is top notch.

The clips that hold the wiring to the bracing behind the seat can be tough to find also. If you can't find them, you might try using dome light wiring clips that clip on the sail panel behind the headliner, or trim down some cuda roadlamp wiring clips which are also available from Mike at BE&A.

Oh, I almost forgot, you mentioned putting the optional clock in your 70 Challenger standard cluster.

This is the correct 70 Challenger standard cluster only clock. (either style would fit & function, only lettering/needles are different.)

Tav

for comparison, here is the 71-74 Challenger & 70-74 Barracuda standard cluster clock.

I've heard the clock set knob itself and tube nut are the same as used on a rallye dash and are also available reproduction from Mike at BE&A if you need them.

Tav

I'm pretty sure the clock I have is a '71 style. I don't know if the car came with one from the factory or not as there was a Rallye dash in the car when I bought it. There is no indication for tach on the fender tag so I figured the car came with a standard cluster. I never liked the blank plate on the standard dash where the clock should be so I pulled the clock from my Cuda's standard cluster as I plan on putting the Rallye cluster in the Cuda (too much Black otherwise, needs some woodgrain to dress it up).

As far as options go it is definitely an odd ball car. EB7 with the V1G top. 383 2bbl motor. Power Windows, AC, Molding Group, and AM/8-Track for the main options. I don't remember seeing the Rear Defogger on the Fender Tag, but the car had it when I bought it so I'm keeping it. The car is an LA plant car and also has California emissions.

Sounds like my kind of car.

I agree, it probably came with a standard dash.

Rear defog didn't require any sheetmetal changes, so it probably wouldn't be coded on the fender tag. No way to know for sure without the broadcast sheet.

I'm curious about your molding group...A63 right? What other M codes appear on the fender tag?

Tav

There is no A63, only the M21 Drip Rail Moldings code on the tag. The car has the stainless trim around the grill opening on the front valence, as well as the back of the hood and fenders, and top of the doors (belt molding).

Joe

That's interesting. Since those molding require alterations to the sheetmetal of the car (holes in doors & quarters), they should be on the fender tag. An SE car would have M31 on the tag, and a non-SE with that trim would have both A63 & M31 I think. I'd have to suspect they're not factory on your car, but since you've got them, might as well enjoy them. I know I would.

Does your car have the astrotone tailpanel molding (like the SE's) that also came with the A63 molding package? Does your car have rear seat ash trays?

Tav

Car was repainted so I don't know about the astrotone. No rear seat ashtrays.

Joe

The astrotone tail panel molding is a very large aluminum trim piece that covers all of the tail panel above the tail lights and both ends of the tail panel trim on the quarters are grafted into it. It requires extra holes all along the top edge of the tail lights for clips to hold it in place. Doesn't sound like you have it on your car. If your car ever had it, and doesn't now, then the sheetmetal holes for the trim clips would have had to be filled to keep the trunk from leaking.

Tav

I know it is an old thread but very informative and worth bringing back.

Does anyone know what the difference it between the fader that has the 6 prong plug on the back, vrs the fade that has wires attached to it?

So any chance you can tell me which one this is?

That's a mono fader .Notice It only has 3 wires going into it. It is used on AM cars with a single front and single rear speaker.
On the 1970 E body ,a stereo fader would be used with a 5 speaker system , 3 in the dash and 2 in the rear. It would require a diffrent harness as well which would include a crossover box.

Great old post on the wiring of challenger cuda stereos including the use of the crossover box.
thank you

I know this is an old, old post but does anyone have a wiring schematic of the crossover box internals? I haven't been able to find a complete box and am probably going to try to make one. Thanks.

Edit: Just bought one off Ebay, I'll find out what's in it!
