If you were just going to throw the carrier back in and spend no real money on it, I'd say run it, ust be EASY on it.
If you want to "upgrade" it by spending money, start with a better base. It would be like throwing a weak crank into a $10,000 race motor. The motor is not going to last, and your $10,000 just went down the drain.
I took a sawzall to one of my 8.5's to get the pin out (just cut right next to the pinion shaft) and I was thinking that I could *probably* run it as is. But since I wasn't needing the open carrier, I scrapped it.
Buddy has an S10 Blazer we replaced the 7.5" in. Gov-lock before and after. I cracked the carrier trying to shear that pin by pounding on it with a drift and hammer, (I was new to this) then I took it back since the thing was guaranteed to be "good". No, I didn't feel bad about that, since I needed to get the brake backing plates off, it WASN'T good. They had the pin drilled out, and we re-installed it. Like 4 years ago. /forums/images/graemlins/smile.gif Still running and driving every day.
