Anyone have a photo of a 70 rally dash frame?

Now in regards to the radio.

I assume you want to go back to original. So one word about the radio.

The radios in 70 have the same mounting face as the 68 and 9 cuda which is unique from all other car lines and models .......however the correct one for 70 will have a face plate that says "Chrysler Solid state"

In the 60s Chrysler used face plates indicating the division and model it was installed in (dodge solid state, Valiant solid state......etc.) starting in 70 they were pushing to standardize more parts to cut production costs so starting in 70 the Plymouth cars and the dodge cars all said "Chrysler solid state" so the 70 radio with that designation is correct for the dodge swinger 340 and the Plymouth duster 340.

If someone tries to sell you one that says "Solid state by Plymouth"...that came from a 68 or 9 cuda and it will bolt up but its not correct ( I don't know how correct you want to be but just be aware.)
