Used BOSS 302 Flywheel. Gear teeth are in great condition. I don't believe the surface has ever been cut, but I can't say for sure. PN C9ZE-6375C. Also stamped C9ZE-C elsewhere. Date codes R...A...O...LD I do not know what they mean. It has some minor surface corrosion and hair line cracks or checking. I believe these can be removed with a resurfacing. I did my best to get everything in the photos, but if you have more questions just ask! It was bead blasted and coated in a anti-corrosive treatment for storage, hence its yellowish appearance. It can be cleaned off.
