Hello, you need a bellhousing, inspection plate, block plate, clutch, clutch fork, throwout bearing, clutch equalizer and mounting stuff for it, flywheel with bolts, starter, pedal assembly, shifter assembly, shifter plate, linkage, insulator, 4 speed tranny, tranny mount is also different, if you use an 31 spline toploader you can use the yoke from the C6 if you have an gt500. Driveshaft is different on a GT500. For the value I would say its the same as long you use Fomoco stuff.
