I've searched this subject but haven't really found any thing on it. What has anyone done for a driveline setup on a 62 Impala. The car is going to have a built LS1 and 4L60E trans with a 9" rear. I have heard the stock setup tends to break fairly easy and am looking for something that will last.

Are you talking about the 2 piece driveshaft, the 3 link panhard bar rear end setup? The stock 10 bolt pumpkin rear?
Inland Empire makes stouter 2 piece driveshafts and a urethane carrier bearing.
Global West as well as Hotchkis make some rear control arm setups. There are many drag cars in the 10s with a factory setup, usually just adding a 4th link(2nd upper)-what the factory racers in the 60s did.
The factory 10 bolt pumpkin rear starts giving up around 400 hp with any kind of sticky tires. They have a poor spine count axle, some guys swap in a Dana side gear to get a better axle spline count but the pinion still has only a few.. Most guys using more HP swap in a 9", 12 bolt or the nostalgia guys and old Pontiac/Olds rear. Currie makes the 9" with upper brackets for two upper control arms as well as adjustable control arms.

Or Show Cars has some rear end parts esp for adding the 4th link.
