Safing brackets are a MUCH better solution. When the retaining pin (the little one) breaks, it is breaking because the spider shaft has seized to one of the spider gears because of thermal expansion. When this happens, the spider shaft spins with the spider gear, and shears the retaining pin. While it stays hot, all is well. When it cools down, though, it unsticks itself and backs out of the differential.
Think about it this way. If the spider shaft is welded in place, what happens if it freezes into the spider gear? Best case scenario, it spins inside of the gear, wearing and galling. Worst case scenario, it snaps either the weld or the shaft, and you wind up with a normal differential explosion. What is the improvement in having a welded spider shaft?
With safing brackets, if the retaining pin snaps, the pin stays in the differential. It is a huge improvement over having the transmission case being torn apart.
Here are my recommendations for preventing a differential explosion: Don't do burnouts (duh) weld the spider shaft <shudder> (don't like) Safing brackets (like a bit better) aftermarket spider shaft slip in differential slip in differential with safing brackets slip in differential with an aftermarket spider shaft RetroFit LSD conversion (GREAT!!!!! Best bang for the buck, in my opinion) Quaife (all around best option, but 1300 smackaroos is tough to swallow!)
