Default 12 Bolt ring and pinion

Does anyone know where I can get stronger 3.73 gears for a 12 bolt? I have been using Richmond street gears for several years and have had to replace them at least once every race season. I keep breaking teeth off of the ring gear. Richmond sells Pro gears but the closest ratio I can get is 4.11. I don't want to gear any lower because I am hitting 6100 rpm at the end of the quarter mile and don't want to rev my 455 2-bolt main any higher. I can't get any taller tire than 28x10.5 under my Bird. The 3.73 must fit a 4-series carrier since I am using a spool. Richmond will not let me special order them in Pro series. Any suggestions? - Kyle
