I have to agree that obviously no one would be purchasing an 8 track for their truck because of the amazing sound quality and high tech design.... You may as well ague about buying a gen I small block over today's engines as being a stupid idea...
That being said - many people - myself included - are on the hunt for rare period correct accessories. And to me the pinnacle of period correct accessories are those produced and sold by GM. Must also be the same opinion of many others based on the successful sale prices of these accessories on ebay.
In my opinion - that 8 track is worth $1000 -- to the right buyer. The GM cb radios are even starting to sell for as much as $400 for these trucks. Speaking of that - someone got an amazing deal on a NOS gm cb for the 65-70 ish year trucks on ebay recently - $150
There is another 8 track for sale on ebay for 67-72 trucks that looks a little different. It looks like those that came in Cadillacs and when I asked the seller why he thought it was correct for 67-72 trucks he said he had install instructions and all the dated documentation specific to 67-72 trucks. I know everything I've read on this forum says the above pictured 8 track with GM on the door is the only correct one - but looks like the one this guy has may also be correct.
