Dash plastic

[1970 FM3 Cuda]

I am finishing the build out of my black dash, it is a 1970 cuda' no AC car rally dash. I have different part number for the left and right side lower black plastic pieces. These are the final pieces that go around the heater controls and the radio. The part numbers are below. I need to no which part numbers are correct for my car. Car was built in April. These pieces look the same expect for a molded ridge on has it and one doesn't.  I am assuming both -B go together.

Left side part numbers   
•   2984045 74086
•   2984025 74086-B
Right side part numbers
•   2984044 74086
•   2984026 74086-B

Thanks

70 Challengers had different dash trim from the other e-bodies.

Below is what was for a Barrracuda / Cuda 70-74 and Challengers 71-74.
I'm guessing the "-B" has the "added ridge"

thank you, so if it doesn't have the grove its 1970 challenger only.

thanks

Correct.

Here's a link to Tony's parts reproduction versions of both.

So the 70 Cuda was just like any other 71-74 Cuda in regards to the pictured trims, only the 70 Challenger is different?

YES, correct

No wonder that after 71 they went cheap on the side marker lights on everything, they had to pay for all these one off 1970 parts

The same side markers after 71 were used Corporate wide, A,B,E etc... depending on car model. Also for Federal safety standards mandates.
