c6 whats its worth?

so im taking the good reliable c6 out of the car and bought a glide, as the chassis i was doing is just about done, my question is what os the c6 worth? its was new from transmission specialties, all the goods, kevlar bands and clutches their reverse manual valvebody and transbrake deep pan, servo and all the goods that they offered at the time, bought new, refreshen every 2 years, was behind a bbf making little over 900 hp, no problems still good only reason its being pulled is i went full 4130 chassis and set car up for supercomp index. otherwise it still be run.
whats the going rate for these now and whats it worth.
