Okay...
So now you've installed your vintage OEM 8 track player
and you finally get to crank that Del Reeves truckin' tape you've been waiting so long to hear BUT!!! You notice your fake woodgrain case loaded with cassettes... what do you do now???
Easy... you whip out your vintage 70's Radio Shack "Stereo Cassette Adapter"
Slam this puppy into your 8 track player, insert a cassette and crank it up!
