1970 Challenger Dash Light Bar (differences)

[Cuda Cody]

The 1970 Challenger Light Bar was unique.  Both the Standard (3 light bulbs) and Rally (4 light bulbs) Light bar for 1970 Challengers was different on the ends compared to the other E-bodies.  1970 and up Cudas and 1971 and up Challengers used used the same the same light bars.  Not sure why Mopar did it that way, but here are some photos and part numbers to help you identify ebody light bars.  Thanks to @Jay Bee  for the photos. (Also, there might be a later 72+ model year part number change too, these numbers are for 1970 and 1971)

• 1970 Challenger Standard dash (3 bulb housings) = Light Bar #2984 166 (See Photo 1 & 3)
• 1970 Challenger Rallye dash (4 bulb housings) = Light Bar #2984 081 (See Photo 1 & 3)
• 1970 Cuda & 71+ E-Bodies Standard dash (3 bulb housings) = Light Bar #2984 126 (See Photo 2 & 4)
• 1970 Cuda & 71+ E-Bodies Ralley dash (4 bulb housings) = Light Bar #2984 187 (See Photo 2 & 4)

Here's another pic that may help.
The 70 Challenger light bars are curved to match the different shape of the 70 Challenger dash pad foam.

The 3 screws that fasten to the metal dash core are identically located on all E body light bars.  The curved part of the 70 light bar is recessed to allow these screws to be in the same place as other E body light bars.  This allows the metal dash cores to be identical for all E bodies.  The dash cores can be drilled for options like air conditioning or stereo speakers, but they'll fit in any E body, only the foam is different.  If you need a 70 dash core for restoration and you can only find other E body cores, you're still ok to send it in to the company of your choice for new foam & vinyl.

This pic illustrates the difference between a Rallye light bar and a Non-Rallye light bar.

Different number of lenses and different color of lenses.

The extra bulb seen attached to the left hand end of the Rallye light bar in this picture is the Title Lamp that's only available as part of the A01 Light Package option.  It could be installed on cars with or without a rallye dash.

Here's the back side for reference.

As far as I know, the 72-74 part numbers are the same as the 71 part numbers.
The rumor that they were different came from a misunderstanding that Jules D'addio had. Jules thought that Rallye light bars were for 70-71 cars, and non-rallye light bars were for 72-74 cars. He was confused because he was only sent light bars to restore, and didn't get to see the cars much. He posted that info on another Mopar forum.  We got him straightened out about the light bars, but MCC copied the bad info from that forum and put it into their book, distributing it to many other people. 
The MMC book is always a work in progress, so I hope this error has been corrected in it by now.

You're welcome! 

I've been busy working on my 70 Road Runner.  Getting close, might start it up in the next week or so.
I couldn't resist this topic though.  While I'm here, I guess I'll look around a bit and see what I've missed.

               Got any pics of the RR ?

I didn't want to hijack this Challenger dash light topic with Road Runner pictures, so here's a link to a whole new thread just for that car.
