What might these parts fetch?

I have a 71 240z R180 diff housing in excellent condition (cleaned and painted) but without side covers (they were mysteriously misplaced). It will include a 4:11 ring and pinion in excellent condition too (pinion is already installed). I have a two sets of 6 bolt output flanges and one set of stock 4 bolt flanges for a R180 diff. I also have an original NISMO CLSD for a R180. It is in need of a rebuild but all parts are available according to Tidewater Z. This R180 was removed from my Z for a rebuild but I wanted to change the r&p to a 3.90 so I opted for a R200 conversion (with a Quaife diff). After the fact, I would have been $$$ ahead to just rebuild the R180....oh well.
