Used automatic C6 transmission flex plate from a Q code 351CJ engine. All of the Q code automatics, or 351 Cobra Jet engines, came with this flex plate for mounting a specific torque converter. This flex plate has the torque converter mounting holes on a 9-1/2 inch pattern. Sold in used condition, may need a fresh ring gear. The current ones in stock are serviceable, with little to no damaged starter teeth on the ring gear.
