I agree. At least go to a beefier rear axle. You can buy 14 bolts for less than $200. D60 fronts are another story, though.
The engine in my project made 370 hp and 408 lb. ft. of torque on the engine dyno, so I ditched my D44 rear axle and replaced it with a 14 bolt. Since I sunk a bunch of coin into a Waggy 44 front axle, I'm stuck with it for a while, but someday I'll replace it with a D60.
