73 Rallye gauge cluster

[RJChallenger]

Im thinking of going back to a 2 spd wiper system and non rallye dash. What is a 1973 rallye gauge and switch set worth with a wiring harness to fuse block, and 4 light light bar. All gauges ad switches work.  Am I better off trying to sell as a package or individually. If I dont switch back to original factory setup, what would a 2 spd park systen ( crank arm 2822290 and 2893014) with drive arm 2822 292  58622 be worth. This wiper system has not been used since 1977 when the car first came off the road
