I'm doing my own conversion i.e. taking out the middle bench seat

I'd wanted to keep the seat in case I changed my mind. However, I have simply no place to store it.
I could try selling the seat on ebay but I'll get almost nothing. It might take ages to shift too, if at all. I don't think people want them.
So, I'm left with option of throwing it away. It seems a sad thing to do though, as its quite a structure and in nice condition.
Any thoughts?
