A/C Set-up for a 67-72

[LUV2XCLR8]

I see them all the time used for $100-$200 and I know you can
go aftermarket for $900+ or so, What is a set-up worth that is
used, but includes ALOT of new parts? (I think the condensor,
accumulater, hard lines, heater core, & blower motor are new)
The compressor, brackets, soft lines, etc........... are all used.
+ anything not needed to go aftermarket (Except Controller)

I'm going to go aftermarket and just want to unload it quickly.
