I've been out of the F-body scene for a while and have performance suspension stuff left over.

Midwest Chassis subframe connectors, weld on, powder coated red. Never installed them, never even removed them from the wrapping. I'm not sure if these actually fit third gens, I bought them for my 94 Z28 at the time. They're $170 new, I'll let go for $125 + shipping. https://midwestchassis.com/products/...-powder-coated

6061 solid aluminum LCA and panhard bars, fully adjustable on vehicle from both ends, with custom stainless steel bolt bushings and kevlar self lubricating races and boot seals. These were custom made for my drag setup at the time, maybe 20 passes on them. These are very heavy duty. $450 for all three plus shipping.

 

How much lighter are the aluminum bars compared to steel?

 

They're comparable to the factory steel ones. I haven't had any aftermarket LCAs to compare against, but since most aftermarkets are hollow I'd say they're probably a tad heavier. If you're looking for weight savings these probably aren't it. They're meant to be the strongest option for hard launches and racing.
