I know this is a long shot.
The car is a 70 R/T FC7 JS23UOB202817
It runs and drives fine with a 76 440.
But I’d like to find the original 440.
The party I purchased it from said it was a Missouri car.
Looking for the block or engine.
Thanks CJ
I'm including a video of my dash with what looks like previous owners remedy for a new stereo.
My car is 8 track, 3 speaker dash, rear speaker equipped.
It looks like some wiring was cut out from the drivers side eliminating the rear speakers and switch.
The switch and wiring are still there...
The previous owner chopped this up pretty good
to install a manual trans for some reason.
I have an old trans hump sheet metal piece with partial
cross member that should weld in place fairly well.
It will take some fitment to get it right.
If not it looks like I'm shopping for some parts at AMD.
