Broke my axle again.. help?

[dynevahn]

Hey guys I have a 79 sc body with a 3.3 930 engine. I posted awhile back about my right side axle bolts breaking and it happened again. First time I dropped the clutch like an idiot, this time I came off the highway and hit about 4k rpm and it just broke. The guy who changed them put a used axle in and replaced the bolts. My question is there a turbo axle kit from left to right that will mount up to the 5 speed tranny? Car pushes at close to 510 hp to the wheels. I can understand why it has broken. If it matters what has been done, kokeln turbo/intercooler, fuel head mod, alcohol injection kit, nitro booster(stuff actually works) 114 octane, full exhaust with no cats, 1.2 bar, fuel enrichment system, tial wastegate, aftermarket bov, fabspeed bmc filter kit, sc cams, igntion timing advanced to 35 degrees at 6k rpm, msd igntion, and magnecor wires. I have front and rear sway bars, and front strut bar. I need to upgrade the axles if possible. Is there anything pelican parts sells that I can use? I need something asap. The tranny was rebuilt 2 years ago and the clutch is practically new. Im not too worried about those breaking, any input would be greatly appreciated. Thanks

I would say to check out the hot rod community.
Pinning the flanges, using SPS 6800 series bolts, special lock washers, etc.
If it's done right, you can hold 4500HP!! (The rails do all the time).
Also...look into the aircraft industry for hardware.
Good luck.
