Large Sector Manual Steering box source

my Van has a Manual box (1972) and its the large sector like you'd find in a C-body. Napa shows the part number, but they haven't any in stock at all. I know Firm Feel has a kit but I'm not sure *I* want to rebuild something like that (yet)

Any other sources for these with core exchange? Its shot..

I have a NOS van box in my shop, don't know what it's worth though.

Whatever you want to sell it for I guess.

EDIT, if Napa was going to have it it would have been about $120 with a core. I was all about that.
