8 Track player is all i use, just love it .You can buy a nice small one under dash on e bay sometimes cheap .I bought mine there and it was new in the box .
I have to dig around somewhere in the attic I should still have a new am/fm 8 track in the box.not a brand name one. Bought it back in the mid eighties. I do for sure have a 8 track recorder you could make your own 8 tracks.
