I have a 1st Gen S/C with a bad nose drive that I am selling as a core to be rebuilt. Was removed by the dealership and returned back to stock. Everything that was used to install the S/C was returned to the original box.
Nose Drive kits are available to rebuild it yourself or send it to PSE in OK for a full rebuild to new for $700.
For a total of $1500 you get essentially a new S/C...which is half the price of a new one.
