8 3/4 goes boom

My ring and pinion went out last night at the track. I was very careful to replace everything in the driveline of this car with stuff that could handle the horsepower, EXCEPT the ring and pinion gears! So Murphy's law has struck! The rear end has Moser yoke, spool and axles. Would like to replace with same gear ratio, but something stronger than stock.
Any suggestions as to a brand? Moser? Richmond gear? It needs to be able to handle about 800hp or more.
