New to me Hesston 6450 swather

I just bought a Hesston 6450. It runs good and cuts pretty good and I like it. I've wanted a sp swather for a while. No I didn't need it but I wanted it. I found another one that would be a good parts machine but it has no header with it. My question is do any of you guys know of a place where I could get a header in working condition in case I decided to fix the parts machine? What do headers usually go for? Thanks in advance
