This is a Tremec TKO 600 with blowproof bell housing , mdl single disc clutch, tilton adjustable throw out bearing, zero balance flywheel , pro 5.0 shifter, hurst shift handle and 5 speed shifter ball. I baught everything new for an N/A big block Chevy but since added a procharger so I upgraded to a t56 magnum. Trans only has about 500 miles on it as you can tell as the clutch looks new. Car is a weekend cruiser. Price is firm for everything. I have also have a box of extra items if needed from MDL at extra cost I was going to return if convertering from an automatic like shifter boot and ring, pedal pads, trans tunnel, and misc connectors.
