I also have a getrag 240 5 speed
works great fresh AMSoil fluid no grinds, shifts very good.
It was converted to internal tilton TO setup.
$350 without the throw out.

I have a matching tilton twin plate clutch setup for m10 or m30 motors.
Stock modified flywheel with ARP hardware.
Tilton hydraulic TO and stainless braided clutch lines.
Clutch has maybe 7k miles and its in great condition.

$650 for the whole clutch setup

Edit:

Part#s for the clutch

Clutch cover/Pressure plate: 66-302UW

Discs: 64185-8-VV-10

TO : 60-1280

Clutch is rated for 480 torques but can be easily upgraded with different pressure plate to handle up to 900lb-ft.

You can get the flywheel form Rhama RHD for your high power s/m5x or m20 to run this clutch.
