1988 IROC rear axle help

Just finished a resto on a 1988 IROC. Did some mods to the original engine and now find the gears in the rear axle are not up to snuff for the performance I want. I am told the car has a Dana rear axle w/ 2.73 gear ratio and parts for these units are hard to find. Anyone know if there is a 3.55 or 3.73 gear set for this rear axle? It is the original one and do not really want to swap for another axle.
