I had a circa 1973 Craig powerplay 8 track... a big thing...this is dumb but I cut out bottom of a Kleenex box to slip over it when I parked
Mine came with a slide-in holder so I could remove it from the truck.
I remember festering over which 8 track player to get. Only had a few bucks left over to buy maybe two 8-track tapes. Played the hell out of them. One was Trilogy album by E,L & P as above, and the other was Led Zeppelin IV (with the old man carrying the bundle of sticks on the cover). Stairway to Heaven...
