NOS GM Clutch # 3959176 / what's it worth

[SOM_Firehawk_02]

Just cleaning out my garage trying to move some parts I don't need anymore and I found a clutch and presser plate that I think I ordered for a 69 Camaro that I was working on. GM Part number is 3959176 can someone give me some feedback on what it would be worth?

Thanks for the help,
Ken
