Looking to get tunes back! Bluetooth or wired or whatever.

Another option might be to find the smallest amplifier you can find (Walmart or Best Buy). Get an adapter cable to go from headphone jack to Mono-in to amplifier. Run a speaker wire from output of amp to your dash speaker.

I don't know what size your dash speaker is, but on my '71 C-10, it had a 4x10 mono speaker in the dash. I found an option that had two 3.5" speakers mounted into a plate that was cut to the standard 4x10 speaker shape. If you did that, you could get a simple Headphone to RCA adapter cable to feed the signal to the small amp, then run right and left channels to the new twin-speakered dash speaker giving you stereo sound. Bet you could get all of that for around $100.
