Is there any market for these? AM/FM Cassette from 1994 model, radio works fine no idea about cassette player, haven’t bought one since about 1993.
Yes and no. If the price is wrong someone that is looking for one will just go to the junkyard. See if the local yard has the parts price list for your truck.
Funny you mention that, I see people posting about hitting boneyards for parts pretty regularly on here but the local yards around me very rarely have anything as old as the 90s here. Most everything has been crushed for years and years here.
