2.94 or 2.76 gears 489 case

Looking for a 2.76 or 22.93 gear set for 489 case. Would consider complete center section or gears. Possibly also consider a trade. I have a 489 case with Mark Williams caps and 4.30 gears with a spool and 35 spline axles for a body rear. Would trade for a sure grip with gears and axles
