MONTE CARLO How does a 7.5 rear end die?

[zz4-84MonteCarloSS]

I've heard that with the 10 bolts rear ends the axles will walk out and destroy your car with them. I was wondering if this is true for the 7.5 as well.

I'm current building a 84 monte carlo ss that's gonna have around 450ish crank hp with a 350 sbc. And I want to know if just sending the rear end without replacement is just a totally bad idea. If it's gonna explode and take me and the car with it I'm definitely gonna look into a new rear end.

So what number carrier do I have with the 2.73 gears and which number for the 3.73 gear set.

2.73 gears fit a 2 series carrier.
Carrier break is series 2 (3.08 and down) and series 3 (3.23 and up).
So, your 3.73 gear set would need a series 3 carrier.
