When I ran 8.2 the failure points for me was spiders and wheel bearings.

Haven't run one in a long time now

Default TA originator of differential girdle ?
John Geis owns the patent for differential girdles in the mid 70's as I was a dealer. They do work. I ran my Firebird into the nines with a 12 bolt with stock caps with no breakage.

I work with a lot of electronics, so we use in-lb and even in-oz measures all the time. 60 in/lbs is pretty significantly more than finger tight. For reference our screwdriver type tq wrenches only go to 50 in-lbs and it’s a bit of a bear to get that number out of them. Or course it won’t feel like much with 12 or more inches of leverage, but compared to hand tight it’s quite a bit.

John Geis did the Geis Girdle, believe initially in the 1960s.

Ken Geis is a Carb Guy, (Q-jets) on the east coast.

The Geis Girdle worked great for many GM people.

Too expensive for me in the 60s, I just bought another GM rear out of the junkyard.
Course I was making no real power then.
