JC Penney car air conditioner

I have a 67 Skylark that I bought for a parts car and inside it has a aftermarket AC unit sold by JC Penney. I was 3 then but I had no idea they sold these items back then. It has copper lines that pass through floor. Should I keep it or just let it go with the car after I take the parts off I need?

 

If you're not going to use it, I'm sure it would be worth something to a collector. Try eBay.
