What's it worth? 67-69 Camaro NOS subframe bushings

[BillD]

I have a complete set of 67-69 Camaro NOS subframe busings that I purchased probably 25 plus years ago from Jim at Heartbeat City. I know the radiator support bushings are the smaller diameter original style not the larger replacement parts. I had been saving these in the event I do another car.......that is not going to happen. I have not been able to find a recent sale on these to figure out a price, as I see no need for keeping these. Any ideas on what these might be worth? Thank you for any help.
